This is an introduction to the basics of VSEPR Theory. VSEPR theory is a set of rules for how to look at a Lewis structure and determine the three dimensional (3D) shape of a molecule. The shapes have to do with the location of bonds and lone electrons pairs. In this video, we'll look at the following shapes: linear, trigonal planar, bent, tetrahedral, and trigonal bipyramidal
hey sir
i dont know ur name
but i am highly obliged that u r making such helpful videos
pls keep it going
dont stop it
its helpful for the students who cant afford tuition like me
thanks again
i want to request u to further explain how air pressure effects us
or what is the prove that atmospheric pressure is forced on us coz we dont feel it
thanks again
i already have a video on this topic. it’s called “atmospheric pressure.” thanks for the kind comment, and good luck!
Thank you soo much for uploading this video! I’ve gained the confidence to answer the questions in this chapter 😀 Oh, and I can’t seem to find the videochemistrywebsite 🙁 Has the website been taken down?
Awesome video!
ps: I think you mean 120 degree between each bond in the trigonal planer 7:51…Right?
thanks for pointing that out! i just made a video annotation so that it’s clear that it should be 120º.
Thanks for all these video you’ve been uploading, you’ve helped me so much to understand science without having to listen to waffle!
kkkkkkkkkeeeeeeeeeeeeeeeeeeppppppppppppppp uploading
@ 1:36 you say opposite charges repel, I think you mean “like charges repel.” Great video though!
Thanks for the video. You explain it very well. The props work wonders!
Wow, such a helpful video, thanks!
rock on !
SO COOL
You are literally a life saver. Someone give this man a drink
that’s solid man. you jus explained erry thing in 20 min. my proff was tryna do it for 2 weeks. 2 thumbs up!!
How can you not like this video, you saved my chem grade!!!
So helpful thank you
you sound like you would be a responsible father..
your two cameras are distracting
tough. don’t watch it if you don’t like it.
You’re not a big fan of constructive criticism, are you?
The videos are awesome. i tried thenewboston and khan. i prefer you over them any day of the week. i also appreciate your work A LOT. however, seeing you gesticulate is distracting for me and thus MIGHT be for a lot of others too.
I thought your goal was to reach as many people as possible and maybe to monetize your work eventually. In that case you should ask your “customers” what they think. In any case it’s not a big deal and I’ll keep watching your stuff and hope you’ll add more.
btw: will your webpage be up again? is there another way to see a list of your videos in order?
Excellent models, great explanation, very clear, and enjoyable. You rock!
i dont usually comment on YouTube but i must YOU SIR ARE a blessing from God and keep in mind i appreciate your work. it has helped a lot…ignore those 14yr olds who crticizing your hardwork.
1:40… Opposite charges attract, like charges repel. Otherwise very good video, love the two cameras
thank you so much!!!!!
ur the only person i could understand from without ODing on adderall! LOL! thanks a lot u made the biggest difference in my grades and continue to do so! (:
THIS IS SOOOOOO HELPFUL OMG
I cannot express my gratitude for your videos. My college professor is brilliant, but, sadly, not a very good teacher. You explain things so thoroughly and carefully. Can you share about yourself? ie, where did you go to school? Why you decided to help out those of struggling so much with some of these concepts? Thank you again!
Great video. Couldn’t really follow my professor when he was lecturing about this, but you explained it in a clear and concise way that I could easily understand. Good work!
Thank you so much!!
Dear sir, i am studying a diploma in chemistry and your videos are really helpful. I sincerely do think that you are knowledgeable and passionate about the subject. I also admire the amount of effort placed in each video to help us students learn. You carry out your lessons professionally and your 2 angle camera makes it really personal!
safe dude
I’m a chemistry teacher in a high scholl, I think this video is fantastic, it can help students to learn
Chemistry, very thanks.
It is a FANTASTIC video.
sorry for my english, I’m spanish
my chemistry prof sucks at explaining, so thank youu so much! really helpful with all the props and stuff. THANK YOUUUUU
is there a certain order i should watch these VSEPR videos??? i really do want to grasp these concepts!!!!!!!!!!!
1) Start with this video.
2) VSEPR Theory Practice Problems.
3) VSEPR Theory: Common Mistakes.
4) VSEPR Theory: Trigonal Bipyramidal Family
5) VSEPR Theory: Octahedral Family
6) VSEPR Theory Practice Problems: Advanced
you are awesome!! thank you so much for these videos… my college prof sucks… you rock!!
lol how ehehehe just focus on one at a time
hella helpful
lol that was just criticism, there was no constructive aspect of that ahah
you’re a life saver.
ur awesome!!!
All I can say is Wow You are a good teacher. I wish you were my professor, please keep up the great work you were doing for improving academic education.
Your videos are helping me so much thanks.
…also you’re beautiful!
1) make your video a window
2) click and drag window to the side until the right is no longer showing
3)enjoy
I like your videos. I have been sharing with my students when they need extra help. Any plans to do videos on covalent or ionic bonding?
I have been moving my classes toward more student-centered learning, and your videos enable me to “teach” them at home and remediate/enrich in smaller groups in the classroom. Thanks, and great job!
Very helpful and detailed video! Can you make one on hybridization?
This video is amazing! Thank you so much for being so incredibly helpful and passionate when teaching. I am so upset that I have just found these videos as I could really use the help in Gr.12 chem. Words cannot express how awesome you and your videos are!
i’ve been trying to understand vsepr for days, but i understood it after 20-something minutes of ur video..ur better than my professor!ehehe, thank you very much!
THANK YOU THANK YOU THnk you!!!!!
I love your videos! you make it easy to understand!;)
Thank you for making this. It was very clear and it’s great how you lay out the path of what students should be doing next.
PLEASE NOTE: at 7:45, I say the bond angle is 180º, but I should have said 120º. Sorry!
Greatfull
xlnt way to understand VSEPR in different molecules..
ur videos r super cool! n i like the 2 cam!
germanamerican81 is right, he is simply giving some feedback, as I’m sure any decent teacher/tutor would like to get.
why are they for you? these should be for people who want to learn, and if your current system is inhibiting the learning process. then you should respond with equal initiative by listening and taking action.
we’re all grateful for the videos but dont act sour when someone is trying to help make them more efficient
Good job!
The naysayers remind me why I went back to Uni to study Chemistry so I didn’t have to work in customer service any more. Look how entitled some people feel to pick holes in your video instead of taking the time to see the great job you did, for FREE.
Great job.
Thank you!! Very helpful.
This video was very helpful especially because it helped me correct a mistake on a 3D VSEPR model project that i am working on, thank you
I’ve used Brightstorm, Thatchemguy, Mr.Causey, & Cantrell; who all have videos on youtube for people needing help in Chemistry. As far as the VSEPR model goes tdewitt451 has the most indepth turtorial videos. Thank you for this great upload and keep up the good work. Youtube has saved my Chemistry grade by giving people like you a format to help others.
This video is DA BOMB! God, I wish my teacher was as good as you. Everything is so fricken clear!
Thanks man
no, i’m right. because SO2 has three things around the central atom: two atoms (oyxgens) and then one electron pair. so that’s three things wanting to be as far apart as possible. so the angles will be close to 120º, and it’s a little less than 120, because of that electron pair, so you end up with 116º. i’d recommend you watch the video called “VSEPR common mistakes” to learn more about how to think through these problems.
Thank you so much!
Dude you’re a life saver….
thank you that was an excellent explanation 😀
keep making these awesome chem videos
i believe SO2 @ 8:40 is drawn wrong some1 plz clarify
There are actually a few different but correct ways to draw SO2. You might have seen one of the other ways. Is that what is confusing?
thanks for the comment! but remember that beryllium dichloride is an important exception–it’s a covalent molecule, even though beryllium is a metal. and if you think about it, it has to be covalent, because ionic compounds don’t form molecules, and we can only do VSEPR with covalent molecules. does that make sense?
My chemistry teacher is having us do reviews of youtube videos to get a better understanding of our topics. So far I’ve found your videos to be the top of the line and all of my reviews have been on them. Thanks for making them!
Atoms that have the lowest electronegativity are usually the central atom. Hydrogen is an exception, hydrogen is never a central atom.
Ex. CO2
Carbon has an electronegativity of 2.6 and Oxygen has 3.4, therefore Carbon will be the central atom.
Hope this helps! 🙂
This helped me so much! Thank you!
Why aren’t you a college professor
saving my life right now <3 tyty this is amazing.
One thing I like about these video, they’re more organize, better, and not being written on a computer : )
Nice man.Thank u very much.I wish you were my chemistry teacher
the way my chemistry teacher told us is that the central atom is always the first one listed. the only exception to this is hydrogen because it doesn’t have enough electrons to form anything other than one single bond.
Thanks! By the way, I just wanted to know why at 4:25, CO2 has to vbe double bonded to both oxygens. Is it possible for it to be triple bonded to one and single bonded to the other?
Nice!
Good job mate, you really explained this well. Very helpful thanks
sorry, you’re too hot for me to possibly learn anything.
I must admit it was a very clear and solid video. It’s hard to find something with the same Khan Academy quality out there. Thumbs up!
Thankyou this has been very beneficial
Thanks so much. My teacher breezed over this and now I feel I’m ready for the test.
Hi! Your video really helped me because my chemistry is really boring and watching this video helped. I have a quick question. Do the lone pairs also repel from each other?
Yes, lone pairs repel each other, just the same way that bonds repel each other.
THANK YOU for your videos! You really helped me out!!!!
I must say, you’re no bill nye (but who could ever top that god on earth?) seriously though, your videos are very informative and helpful
Life saviour
hello, why is boron 6…. and beryllium 4?
Boron and Beryllium are both exceptions to the octet rule. Boron is happy with only 6 valence electrons, and Beryllium is happy with only 4 valence electrons. The reason is complicated, but the basic concept is that they are very tony atoms so they are happy with a smaller amount of valence electrons.
Nice balls, bro.
2 weeks of my life in 20 minutes. Thanks dude 🙂
awesome broda!!!
it was of great help…
How can anyone dislike your video? I mean seriously!
Thank you so much for making these videos accessible to everyone! I know understand vesper theory! 🙂
God bless. You’re a life saver. Thank you for this!
You make a subject that is so intimidating so much easier! Thank you so much for all your helpful videos! I tell all my classmates to check out your videos on here because it helps me so much! I wish you could be our professor! You are gifted at teaching! Thanks again!
Amazing! So well done, answered all my questions and more! Thanks so much
You’re the best teacher ever! You miracle worker you;)
i should just ditch class, learn everything on here, and go pass my tests.
Thanx u saved my life
ofcourse it is..hotness like that is distracting!
I was gonna fail chem, but seriously you saved my first chem evaluation exam! Thank you!
You say that when two things are connected to a center atom it is always linear, what about H2O that isn’t linear
Question I thought beryllium only has 2 valence electron and Boron has 3.. I checked in my reference table and thts what it shows.. can u tell me why u said boron has 6 and beryllium has 4 valence electrons.. not to prove u wrong, just a bit confused actually
wow, amazing! this deff helped me a lot!
He didn’t say they bad 6 and 4 valence electrons. He said that they are exception to the octet rule, meaning that they are satisfied with 6/4 valence electrons and don’t need 8 electrons.
lone-pair push lone-pair > lone-pair push bond-pair > bond-pair push bond-pair.
A good example of lone-pair pushing another lone-pair is the water molecule.
The 3D presentation does help a lot instead of just drawing over the board with x,y,z coordinates.
so helpful! thank you thank you!
Hi
I have a question if u can answer it I will be happy
how can I know it has a double bond or triple bond like HCN how can it be linear i am thinking of bent how can the N has triple bond and CO3 it has a pyramidal shape
thank you for the vid
Definitely a simple and great explanation. Chemistry should really just be taught online lol This is where my education is coming from!
Thank you thank you
Best chemistry tutorial on Internet. If I win a Nobel prize in chemistry in the future, I will definitely mention about your tutorial in my acceptance speech.
aah! i just dont get where u bring those papers from and like how biggg ur table is to fit all of ’em
u suk…… ur qtn aint clear boy and u aint an american bull shit!!!!
I Love u! U just saved my life!!!! Going for a test tomorrow and couldn’t quite understand it all! Now I got it clearer! Thx a lot!!!
Your efforts to explain the concepts are truly laudable.
Keep it up. Hope you put some videos on Organic Chemistry basics.
Really thanks a lot, ur video save me from common test:)
And his done it again! U’ve made my chem life exciting. I’m a first yer doin pharmacy
Thanks a lot !
Thanks so much, I have a huge chem final tomorrow and your video really helped!
Thank you so much! You have taught me in 20 minutes what my chem teacher has been trying to teach us for 3 weeks! Keep up the good teaching! Thanks again! 🙂
reply? or repel? LOL!
can u make a video to explain dative bond?how to identify the compound that will it make a dative bond or not?how to make a dative bond?
thnx in advance
You’ve made ma love- not like, LOVE- chemistry for the first time in my life! And that’s saying something since i barely passed my highschool chemistry classes. How you teach is exciting and fun and it makes me want to learn more! Thank you a million times!
i love the way he explain chemistry, he is good and cute too
You are wonderful at explaining things, this is by far the best video that I have seen on VSEPR. I will be using your other videos !
Are you sure the SO2 has one single bond and one double bond, it should be two double bonds!
Thank you!
Why isn’t ammonium planar with 90 degrees between the outer atoms? Is it solely because it’s 3D and 109.5 degrees spreads them apart further and as equally as 90 degrees would?
LOL
No, they would certainly not be linear because apart from the 2 bonded pairs there are two lone pairs. lp-lp repulsion is more than bp-bp repulsion, hence the molecule will be slightly bent.. 104.5 degrees…if i am not wrong
such a way of making it stick!
Great tutorial!
This was awesome! I love the visuals! I was struggling and this made it a lot easier!
the visuals were really helpfull
thank you
I liked the video very much
There are a number of equally correct ways to draw SO2. You can draw it with two double bonds, or with a double and a single bond. In reality, the molecule is sort of a cross between those two different versions, but the point is you can draw it either way.
Outstanding video and very easy to understand.. You should be the chem teacher at my school! lol.. Good job 🙂
this was great thanks a lot!
Its AMAZING how you are actually able to make us love CHEM!!
this video has been a great help and VSEPR theory has actually captured my interest!
no teacher that I have encountered till date was able to explain stuff as good as YOU!! #respect
we’ve been doing this all week at school and i haven’t been able to understand. In one afternoon i’ve learnt more than i have all week ! Thank you so much, you make it really easy.
Helped me understand such a seemingly complicated concept! More helpful than my teacher… thank you so much 🙂
THAnks …………….!!!!!!!!
Trigonal is linked to the Sanskrit words “tri” meaning “three” and “gona” meaning “angle.” 🙂
Thank you so much for spending so much of your time and effort into making these videos. You have made this semester for me a breeze. I feel more confident when I leave class because I know I can always come her for reassurance. Thank you so much again 🙂
Respect to you man! , you are even better than my teacher
Hello, not sure if this has already been answered or not – but why does the non-bonding electron pair push the atoms further apart? Why would electrons exert more force than an atom? I find that confusing, and I would love to know the answer.
Thanks!! 🙂
Thanks so much !! really helped me for my test :))
1:40- opposite charges? Repel? Don’t similar charges repel? Meaning neg and neg repel. Anyone else agree?
Great work! Plus more vids to follow up on. Now, maybe explain how energizing molecules, say like water, produces “water lighter than water” from a larger bond angle between hydrogen and oxygen. Hinting on the memory effect h2o can retain after repeated changes between liquid and gaseous states. Please always remind the listeners about the benefits of science for the human race. We are guardians of this knowledge, lets use it wisely.
I think that you are talking about the Resonance that occurs in the Sulfur Dioxide molecule, @Tyler DeWitt. And by the way, the video is great…!!! And I really really appreciate the hard work that you have done, especially on those 3D models of molecules.
You are the best, seriously. Amazing. Thank you!!!!!
I loved this explanation! Even me beeing brazilian I understood everything that you explained.
Thanks a lot!
Because there are two ways to draw it, how do you decide which VSEPR model to use? Or is it the same as resonance structures, and you would say both but its a cross between the two?
Lol you’re so adorable. Definitely make chemistry worth learning
Finally get chemistry :3
i understand Chemistry Ib now
You are awesome!!!! I understood now!!! Thanks a million!!!
Is the double bond in this in continuous movement like that in SO3 and NO3?
Thanks very much !
Maybe you could add links to the related videos at the end, so that the viewer just has to click on them.
Anyway very nice video, comprehensive and all (I’m french and i understand it better than my teachers’ explanations haha) so thanks again !!
well taught.keep it up
bf3!!!! lol joking, this generation is not doomed. Anyways, good video, thanks!
Thank you so much! wish you were my chemist professor
You just explained in 20 minutes what my Gen. Chem. professor couldn’t explain in 3 lectures.
U r amazing n really cute
Thanks so much
Hmm, maybe that’s why you’re here in the first place.
C’mon teach, carry-on.
Good evening Mr Dewitt,
In this video you say that electrongs have negative charges and opposite charges repel each other but aren’t 2 negative charges or 2 electrons the same charge? This is confusing me. I love your videos by they way. I went from a D to high B and still have my final Im shooting for an A! 🙂
ooops I just saw your correction. 🙂
I haven’t seen anyone correct this and I scanned the comments quite far. You’re saying Beryillium “Di”chloride. Beryllium is a metal and prefixes aren’t generally used in ionic bonding nomenclature…Are you sure that is the right nomenclature? Prefixes are used to distinguish between elements that combine in multiple proportions, right? Is there such thing as Beryillium trichloride? Why are you using a prefix here?
like charges repel*
why isn’t berrylium(BeCl2) has a complete octet rule? is this an ionic bonding?
Beryllium dichloride is an important exception. It’s made of a metal and a nonmetal, but it’s actually a covalent molecular compound, not an ionic compound. So yes, what I’m saying is the right nomenclature, because it’s covalent, not ionic.
Hi Tyler, just a quick question. My chemistry teacher has taugh us that structure with 4 bonds two of which being lone pairs is named Angular. Is it different due to being british or has he taught us the wrong structure?
THANK YOU SOOOO MUCH FOR THIS! I have a midterm next week and my professor just goes by too fast! I was so lost and you just saved my life!! THANK YOU SOOO MUCHHHHHHHHHHHHH!!!!!!!!
Seriously saving my life. My teacher was so confusing with VESPR theory. D:
So glad I found your videos!! They’re so helpful!! Thanks
THANK YOU SO MUCH. I AM BEYOND GRATEFUL TO HAVE FOUND YOUR VIDEOS!! Pls continue saving lives like this 😀 <3.
Thank you Mr Dewitt for your time to explain this concept. I will be having my midterm test next week and you’ve really simplified the VSEPR in an unimaginable way! Cheers from Canada!!
Yorku??? PIETRO?!
Dope concept Liam.
If I had not found your videos I would probably fail chemistry! You are an incredible teacher! THANK YOU!!!
This video is extremely helpful!
thanks 🙂
I love you !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
You are awesome! 😀 You have no idea how much this has helped me! 🙂
u said ionic bonds stolen electrons not sharing, and now you say they are sharing…a bit confusing. Ionic vs. Molecular
Shout out to Mrs. Brasington
thank you so much, you save me from my test 🙂
Tank yyou for spending your time and making this video!
Finally, I understand this. My high school Chemistry 1 & 2 class failed to go over VSEPR. As a result, as I was tutoring someone in Chemistry 1 we came across it (he had a different teacher) and I wasn’t able to teach it properly. Since I plan to major in biochemistry, I figured I should take the time for figure it out. Thanks for the video!
TheXtamac how did that biochem degree go
lets wait 2 more years
OMG thank you. Saved me for my exam tomorrow.
This teacher is unbelievable. His explanations are simple and more interesting.
Thank you so much! Great video and great techer, too! You made vsepr so simple to understand!! Keep teaching! 🙂
This is perfect! found it for my high-school son and now my five-year old is also watching the videos with a lot of interest. These are his comments:”This teacher is the best and I love this teacher!!!”
You make awesome videos.
THIS GUY IS Ba! PUN INTENDED! Thanks man I spaced out the last class or two 😮
Literally so helpful for AP chem thank you so much
Thank-you So much It made my concept more clear. Once again Thank-you so much.
helpfull
Love your voice no homo. Makes for a relaxing learning experience. Great job!
ive fallen in love with you…marry me! lol thank you so much im an ace student but my chem teacher sucks and i wad afraid of failing this term. youre a life savior
dude thank you so much!!! you have helped me a great deal (:
That was very helpful!! great job explaining things in a simple way and showing 3-D examples. Thank you for posting this.
your effort made life easy for so many people over the world—-REALLY LIKED IT
Thanks Dude! =D
Really did help so much!
thank u
wish I would have watched this before I got to O chem
perfect! thank you so much!
Lol you also know about chemistry,now I like you even more!!
its likely you won’t get the mark for saying molecule is a ‘bent’ shape. You should use the term ‘non-linear’, as opposed to a molecule with 180 degrees called ‘linear’. Hope this helps people:)
I respectfully disagree. It’s fine if you want to call the molecule “nonlinear,” but “bent” is also a widely accepted term, even in the most technical of circumstances. Look on Wikipedia, and you’ll see that the shape is called “bent,” and I can’t find a Chemistry textbook that doesn’t call it “bent.” Again, I think that “nonlinear” is a fine name, too, but I don’t think that “bent” is a bad term to use.
On aqa papers it allows the mark for “bent”
Great video though, im 100% for exam tomorrow!
Tyler.. At Uni they dedicated 3 hours solid on VSEPR in my Chemistry module (I’m studying Physics) – couldn’t understand it..watched your video’s and walked out of an exam on VSEPR with 90%! You are amazing 🙂 Bri
Thanks so much!
Thanks a lot!!! Great job. 🙂
5 star video. Thank you for your help
only here because I have to be… Nice video though
thank you for this video
You’re my hero… Thank you so much!
thanks!! great help! you are a great teacher much more capable of teaching than all my chemistry teachers together =)
thank you soo much for this video!! i especially love the way you guided where to go from this video…usually its so much more confusing to find other videos related to the same topic. thanks again:)
excellent video!!! THANKYOU SOOO MUCH
very well explained and thorough. One mistake, while explaining the trigonal planar you said 180 degrees and meant 120. still the best video thus far.
Wow u have a gift for teaching for sure
Very useful video I like your style of teaching Its amazing and crystal clear
Can you also post videos on Grade 12 physics problem solving projectile motion and Newton’s laws etc ?? On YouTube?
You helped me soo much Thank you. Can u plz do videos on organic chemistry
excellent
As usual good job and thax keep making these videos they really help!
chemistry eleven honors
I love your videos. they really help! was having a hard time understanding, but you break it down! Thank you sooooo much!
Amazing video! Best by far, now I understand – I was even sick from school (so no notes). Thanks!
LOL bent molecule 2D shape underneath looks like a smiley face
Can you make a video explaining how to determine a molecules polarity?
Thank you so much for this video! You taught me what my professor has been trying to teach our 1.5hr class in under 30 minutes.
I am definitely going to share your page with my classmates! 😀
Tyler, you are the best!
Can you replace my chemistry teacher?
Hey Man! you are a marvelous tutor… Thank you a lot. ……..
thanks! very easy to understand
Thank You. You are great!
Do you have anything on molecular orbital theory or Valance Bond Theory
you say that what “kind of bonds ” isn’t a matter. but don’t the extra pairs of electrons have a significant impact on other electrons?? thank you sir
thank you guy. well-prepared.
Love how you explain everything 👍
can you please make a video about understanding spdf orbitals
isnt it beryllium chloride
No, it is Beryllium Dichloride.
In a covalent compound the number of the 2nd element is indicated by the prefixes:
mono-1
di-2
tri-3
tetra-4
penta-5
hexa-6
hepta-7
octa-8
nona-9
deca-10
so for example:
NO2 is not Nitrogen Oxide, its Nitrogen Dioxide. The Oxygen use the prefix di- because there are TWO oxygen atoms
so that is why BrCl2 is not Beryllium Chloride, but Beryllium Dichloride
I never thought I could understand this thank you so much
No homo, but these videos are soothing. haha
Thanks a lot – you really simplified the VSEPR theory for me :D.
Thank you!!
Thank you so much!!! I’m doing some last minute studying on old topics for tomorrow’s AP Chemistry exam and this helped me remember this topic much more!!
thank you so much
u helped me a lot with it
I was totally lost with it XD
Thank you, it’s very clear! 🙂
I have a question. At 7:40, you mention that formaldehyde has the same bond angles as BF3, but doesn’t the electron density from the two lone pairs on the oxygen repel the two carbon-hydrogen bonds, forcing them closer together, making the hydrogen-carbon-hydrogen bond angle slightly less than 120 degrees, at around 118 degrees or so?
Also, your videos are really helpful! I’m using them to help me prepare for the MCAT!
Maybe there’s a *tiny* bit of repulsion there from the lone pair of electrons on oxygen, but you’re not going to get in trouble for saying that formaldehyde’s bond angle is about 120º. It would be different if the lone pair were on the central carbon.
@Tyler DeWitt I did a theoretical calculation of formaldehyde’s geometry at the B3LYP/6-311+G** basis set just to confirm; the H-C-H bond angle is actually 115.85 degrees, and the H-C-O angle is 122.07 degrees. So you’re right – around 120, just like you’d expect.
Thank you, thank you, thank you!!!
Excellent!!
very helpful!! Thanks
Great explanations given, excellent vid. Thanks very much!
Can anyone figure what is the VSEPR of IF5 with 2- extra charge?
i could understand chem. more through this video!!
thank u!! : )
Why aren’t you my chemistry teacher
Thank you for sharing the knowledge.
you’re doing a great job, man!
Your awesome thank you for making sense of online chemistry.
He is doing a good job but the should explained the reson the angle is less than 120 is becuse the 2unshared of S are only howering around S so that is why they push harder as a result the angle is less than 120.
like mendeleev…using cards..but ur gd….
Thank you so much! I was so very confused. You made it understandable in such a simple way. Thanks for breakin’ it down ;0)
Teaching is an art. This video is like a Mona Lisa for VSEPR lectures. Unbelievable crystal clear delivery. You really take into account the fact that we are students and not scientists. You spoke slowly, pointed and explained everything to the tiniest detail. You need to teach a class on teaching, and if you’ve taken one, it shows in your skill. Amazing.
Imagine hiw lucky is that class to whom he teaches! They should be respecting hin more than their lives:)
dude that’s right
Best description ever for every single video Tyler DeWitt does! … I love the way he teaches so much.
👌 he really should teach how to teach!!
He did deliver a talk on TED
simple and it is helpful
You explained this too well ! You gained my like ! Continue doing more chemistry videos 😀 !
hi i have a quest. how come trigonal pyramidal isn’t referred to as bent?? every other molecules that had electron pairs are referred as bent but trigonal pyramidal isn’t…. thx
Molecules that are bent are ones where you have three atoms in a row, but the row isn’t a straight line. Instead, the line is bent. The trigonal pyramidal molecule is a very different shape from the two molecules that are bent.
THANK YOU TYLER!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I have a question. On the bent molecule what makes the two lone electron pairs settle on one side of the central Atom so as to make the two other atoms less than 180° apart?
Why don’t the two lone electron pairs settle on opposite sides of the central atom so as to balance out the other two atoms back to 180°?
yr video is awesome it makes me understand more thx so much,beside u have a great passion on teaching thx so much
i want to ask why ch4 bond angle is 109.5,not 90
My teacher said Chemical bonds are only attraction force which holds two atom together. They (Bonds) have no any physical existence, Then why do you use long sticks in your model of a molecule? Is She (teacher) Wrong?
can you make a video on hybridisation too??
Thanks for these. I love the way you explain.
sir ur teaching method izz exceelent so m gonna stict to ur channel but i cnt find videozz on molecular orbital theory n valence bond theory … basicaally what i want to say izz i need videozz on the whole off chemical bondingzzz…..plz produce as much videoz on that concepts as u can or if u already have sun1 can pleaz provide me wid d link vry eager for itt… thanku
what?
At 10:20 you mentioned that the un-shared pair of electrons pushes harder on the two atoms. But don’t the electrons in those bonds repel each other?
Btw, great video, thanks!
Wow thanks a ton for all this help you’re doing to people you don’t even know. I wanted to get a brief on my theory for chemical bonding because I end up sleeping in my classroom during chemistry periods and my exam’s coming after two days. Then I came to know about you and your videos 🙂 Thanks a lot for all this effort you’re taking to help us understand 😀 We love you.
Could you please do a video on Valence Bond Theory and Molecular Bond Theory?
Isn’t the angle 109 degree 28 minute in tetrahedral structure
Thank you so much for making chemistry understandable! A few minutes of your videos shave hours of studying cold university’s books.. Be Blessed
sir wat about the structure of cyanide
sir what about molecules with no central atom
thank you. i feel like you are my teacher this quarter
I did not understand his Lewis dot structure for SO2…shouldn’t it have double bonds on both sides ?
i was as confused as you once because sulfur would share 5 electrons when it had 6 valence electrons… just keep in mind one of the oxygens (the one with the double bond), in either resonance structure, gets one electron added to it… also notice that sulfur has to follow the octet rule… thus 4e (single bond) +2e (lone pair) +2e (single bond)=8e
no but can you be my chemistry teacher please
This is the best!!!
When do you know if it’s bent or linear?
I like the content of your videos, but you talk really slowly….. You should try to explain a bit faster.
I love you
Very well done. Thanks!
thanks ^_^
Give this man a noble prize ………….
Thanks! Really helpful
thank you soooooooooo mmmuch….
Thank You! It was very helpful!!
This was extremely helpful. Thank you so much
This video helped sooo much thank you!
Thank you for taking the time to make this awesome video.
I really can’t thank you enough, this video really helped me out. Thanks for taking the time to do it.
Thank you so much! I was having some trouble understanding my teacher’s notes; this video cleared up all my confusions before my exam 😀 got 100%!
sir may i know y only aquaterial atoms are removed in trigonal bipyramidal structure?
in ozone molecule y can’t there be a single bond between all the three atoms?
Because you got off the total number of valence electrons in the compound. Just say like 24 and the central atom X” is surrounded by two terminal atoms such as Y” well first you complete the octet rule and make Y” happy with 8 V.E. so lets say it was a single bond and now you have two in the bond and 6″ are left to go on the terminal so you spend a total of 16 leaving 8″ V.E. You have to satisfy the compound. so say X is not happy after you apply the remain electrons to it for example may say is +1, meaning it wants an additional electron. So, create an additional bond which makes that cloud bond, be a double bond and so. The key is to satisfy the compound. It is more less like you have to balance an equation before working with it. or
This was awesome!!! I never learned this in high school and thought I was screwed in college, thank you so much! I was going to look at Khan Academy, but then I came across your videos and loved it! I will definitely be watching the rest of these in order!
You just saved my grade
Thank you for making these videos. I would like you to know that they are helping me through my chemistry class (:
I am in honors chemistry and your videos help me a lot. I use them to study too 🙂
I just really have to say this. I freakin love Tyler’s ability to explain complex chemistry in such a simplistic way. You are a life saver! My professor knows his stuff but he has no clue on how to teach what he knows to ppl in a way that even a 2yr old can understand and THAT is what you do. I am so ecstatic about finding you and your videos!
do u have any video about molecule electron magnetism ( polar or non polar molecule ) with a compund of three elements,.
really doing great work
I love you!
My boy Tyla just saved my chemistry grade right here
Clear and concise. Well done 🙂
you owe me in chemical
i have a test tomorrow and u made me understand this *100 better, thanks
I have a test tomorrow as well and I am cramming hardcore. These videos are so helpful! Good luck on your test.
Same
ELNikobelic a little late lol look when they said that
Props my man..great explanation thanks.
I honestly wish you were my teacher. Also could you do an oxidation number video (unless you already have, I didnt see it on your channel)? But anyway you my friend are a lifesaver.
thank you for sharing this video, very helpful !
Thanks. For uploading this video. Very helpful
This will probably save me on my exam tomorrow! Thank you so much!! This was incredibly helpful
Awesome! Thanks a lot! 🙂
great man!
honestly really awesome and love the fact that you recommend which videos to watch and in which structure!
Your videos are extremely helpful for my studies especially VSEPER. Thanks a lot!
Can I request u to make some videos on hybridization?
Thanks you!! ≧﹏≦
obvious u wrote vseper but its vsepr 🙂
…
@Alawy Cool haha oops. my lappy loves typo very much
@Jolene Tiew oh ok xD
You’re amazing! Thank you so much
Thanks for helping a lot!(*^__^*)
The textbooks make it so confusing. Thank you so much!
great clarity..thanku so so much!!..
Dude you are the man!! Thanks for all of your help.
thx tyler
why is lone pair is stronger than the bond pair electrons?
No you are looking it at the wrong way. For the understanding of the original question, think of the electron cloud changing size (not density) but size. By contained, i mean the electron cloud is smaller because the two nucleus are containing that cloud, but in a lp, the cloud is less contained so the cloud itself will increase in size and repulse or expand more freely, pushing the other atoms away (such as in water, that’s why it has a bent with a 104.5 degree). For the scope of this question, don’t think about the cloud itself just changing its density, imagine it changing its size. Now it you want to even go that far with the density at all, you’re talking to the wrong person. As an AP Chemistry student, I’ve learned (and still am) that there are just things you don’t question and just accept. Don’t try to over complicate things.
wow, great explaination. thank you very much for this nice explaination. and also thanks for the hard effort of making me understand this
well, i like to know things. youe.r explaination was great. you’re not the wrong person, you made me understand the reason of their larger amount of repulsive force. and i dont believe in the theory that believe what its told to you
Lone pairs are nearer to the nucleus of the central atom and of course nearer to each other than the bond pairs. So their repulsions are stronger.Thanx Sirajum.
@James-Muhwezi its my pleasure thanks to you also.
11:20 Water, also a bent molecule, has a bond angle of 104.5 degrees. Can molecules with the same molecular geometry still have different bond angles?
Yes, but first of all, the reason why water has a degree of 104.5 is because of its lone pairs of electrons that give a stronger repulsion (think of it as a fatter electron domain cloud) compared to a cloud from a bond (since the lone electrons are only attracted to one nucleus instead of two (from a bond)). This is why instead of water being 120, it is less, and the more lone pairs a molecule has, the shorter the angles becomes because of this repulsion.
Now for molecular geometry, molecules can actually still have different bond angles, and it’s similar to the concept of having a “fatter” cloud. For example, the molecule phosgene (COCl2) seems to have a trigonal-planar geometry with 120degree bond angles, but it actually has 111.4; the reason is because it has a double bond. And generally, speaking, “electron domains for multiple bonds exert a greater repulsive force on adjacent electron domains than do electron domains for single bonds”.
However, this is not always the cause, because one of the resonance structures of nitrate ion (NO3-) has a double bond and two single bonds, yet it still has an angle of exactly 120.
Wonderful video! Thank you so much! Hopefully I pass my chemistry test tomorrow. My teacher doesn’t teach us anything. She goes over it quick and if u don’t get it she says oh well.. Thank god for YouTube and u!
helped alottt !!!!
I’m getting an A in Gen Chem 1 because of you!
thank you so much, this really helped me out alot 🙂
Remember, pairs push more
It seems like BeCl2 would be ionic because it is a metal and a non metal but if you look at their electro negativity differences, Be is 1.5 and Cl is 3.0 so a difference of 1.5 makes it polar covalent. I was using the video for my chemistry classes and had to work it out to make sure as I originally didn’t think it was covalent. Thanks for giving me a good resource for my students at home and in class!
Good question! You’re right. BeCl2 seems like it should be ionic, but it’s actually covalent and it’s an important exception to the usual rules.
@Tyler DeWitt Excellent video. Thanks for the work. Why are Be and B exceptions to the rules? Why don’t they follow the octet rule? Is it just these two particular examples or is that a general rule for those two elements?
your videos are so helpful! I’ve been watching them all semester as help with my tests. they’ve helped a ton! Keep up the good work 🙂
This was very helpful! Thank you 🙂
Thank you so much
You’re a great teacher.
This video was VERY helpful ! Thank you, Tyler !!
tyler de witt my nigga
You are the best professor ever! Thank you for your awesome video :)) !!
dude thats such a coll stuff…awsum…
Thank you very much Tyler!! But can u brief me if the two lone pairs of electrons in case of water repel each other? If they do, shouldn’t they be oppositely placed around the atom for the sake of stability?!! Thank you so much!
Thank you very much teacher you help me alot
sir you are expert in explaining all these.
i think it is worth learning from your videos than going to school on a regular basis.
thank you sir.
Vicky Sharma send Bob
Tyler, it is really an awesome video.
This guy is amazing… I never understood chemistry but with his help I think I am getting it 🙂
Would a methyl radical be somewhere in between 109.5 and 107
Thanks for making this video! It’s really helping me understand this concept. I have a quick question – is NH3 definitely trigonal pyramidal? In my MCAT study book it says it is tetrahedral pyramidal, and it also says that on a website I found.
THIS GUY DESERVES 5 MILLION DOLLARS FOR HIS VIDEOS!!!
Com’on.
More like 5.0 x 10^9
he deserves to be taken off youtube you nerd necc
Boy are you giving him
If it’s a yes then go ahead
Sulphur has 6 valence electrons. The figure you drew of SO2 , there are only 5 valence electrons in sulphur atom in that. I’m a bit confused.
Sigma AND PI’S
They actually are the reason for reasons not to be explained here
Thank you my grace.
You are the true king of the seven kingdoms.

IT IS VERY NICE, THANK YOU SO MUCH
Thank You For this !!
That’s ammmmaaaxiinggg
Not many teachers can say they have 100 000+ learners in each of their lessons or lectures.
You can consider urself one of the best teachers out there.
Awesome videos, I fell a bit behind in Science … You helped me catch up.
Thank you. 😉 🙂
Could you please be my teacher? My Chem teacher sucks and I honestly learned more here than with her resources. Thank you for explaining it so well!
not good but the best vedio ever. but what’s for cacO3
STILIANOS HW FOR 2/19 WHO ELS IS HERE FOR IT
Awesome video man really clear and very well presented, thanks heaps 🙂
I just want to thank you! I spent an hour trying to figure this out by reading my textbook and you explained it better in less time!
Great Work…Awesome video and thank you.
Beautifully done. I’m using it for my Intro Chem Classes.
So why, on the SO2 does the O double bond on one side but not the other, and how are we supposed to know the geometry of it if we don’t know why? If you look at the formula and don’t just know this by memory SO2 is going to sound linear..
I have seen your videos and your tedx talk. You are so blessed. After watching these VSPER videos- any question related to it cannot trouble me. I would like to see more videos and I know, you would like to tell many stories. Thank you for doing such a great job. I live in a remote area but your videos keep me alive and connected to the world.
First of thank you for the video it was very helpful and i want to ask in bent molecules which things is pushing away from each other and why?
Your videos are the reason I do well in my chemistry class. I never understand my professor so I have to come home and figure everything out through youtube. The way you explain everything is extremely helpful and easy to remember. I’ve learned so much from your videos!!! THANK YOU for sharing your knowledge! It is getting me through my chemistry class!
thank you!!!
best vid on the internet for this. good job and thanks a lot!
Ohhhh my God. I love you!
This guy has the ability of making a 20 min chem video fun to watch and not boring ! Thanks
hey thanku dude u r awesome….ur concept and ur attitude is amazing…
Very well explained!
Does it matter if the bond is single or double? How does it affect the shape?
omg!!!! I love your videos. I understand things so much better. You make it interesting and easy to understand. Thank you. Can you do a video on equations for chemical reactions, I don’t know if you have that in your videos because I am just visiting your website for the first time. I will definitely tell my classmates. 🙂 I am struggling with understanding how to balance the equations with reactants and products.
A quantity of CO gas occupies a volume of 0.36L at 1.9atm and 299K . The pressure of the gas is lowered and its temperature is raised until its volume is 1.2L . Find the density of the CO under the new conditions. where can I find a video w similar questions I am so lost 🙁
you are simply great..Thank you very much for all your efforts..and prayers
Great video! One piece of advice from one fellow teacher to another – when introducing a concept, try to avoid using examples that happen to be exceptions to the rule. You explained how Be and B are exceptions to the octet rule very clearly so it wasn’t much of an issue, but it adds another level of thought to the problem that you don’t want the student focusing on in the intro.
you’re the most talented teacher I have ever come across, it’s clear that you have an extensive knowledge on the subject and can have amazing communication skills. you have a passion for science and education that’s what makes you a great teacher. please continue to make more videos.
Thanks so much! I have my AS exams soon and I didn’t understand this, but now I do! My teacher doesn’t explain things properly so I’ve had to teach myself the entire specification.
@Tyler DeWitt , I am so happy I found your channel! You can’t imagine how helpful your channel has been for me! You practically helped me pass my Chem classes. I love how simple you explain things and repetitive you make each lesson to ensure we understand. Thank you so much!!!! I couldn’t have passed Chem without you.
Quick question
what elements are the exception to the octet rule?
tyler i hope you have an older brother named booker.
I don’t know if you has mentioned in other videos but I don’t understand what you mean when you say “Adam” and “Cody Alan Bonds”? those are chemical concepts or just names that you chosen? please explain to me, I’d thank you a lot <3
PD: my english is so bad 🙁 My native language is spanish
The two terms I’m using here are “atom” and “covalent bonds.” I have videos on both of these topics, so check those out. Also, check out my videos called “What’s the Difference Between an Atom and a Molecule?” and also “Ionic vs. Covalent.”
LOL I’m so dumb haha, I just read the subtitles intead of listening, thanks
Thank you for this video!
here because I have an exam tomorrow. thank you for the perfect explanation
This is so helpful!!!!
hey Tyler Dewitt, bro can you make a video on hybridization?? P.S. you’ve been a huge help too my studies!
Hi Tyler! I’m from Argentina and found your wonderful explanation, thanks a lot! I teach chemistry at high school here in Necochea, Argentina. Tried to find videos about this subject and failed…up till I found your video. Excellent. I’ll translate into Spanish and will subtitle your video, then I will up load here. It’s so good to find a clear explanation about this item, thanks a lot again….saludos desde Necochea, cerca del mar….
Sorry for my English….I forgot to say that
Three hours my professor tries to explain to a class and no one understands. 20 minutes and one video later I feel like I can win s Nobel peace prize in science ( being a bit dramatic but I digress lol)
My friend, Thank you!!!!
+SimplyBella : exactly, hahaha!!!

you graduate yet?
Love your videos! You are helping me out on so many levels… I have to ask, although I havent watched the other two videos that tie into this one yet… How can one determine which atom the electrons will be closest to? Does that key into the VSEPR theory or is that another completely different aspect?
9:33 why it isn’t two double bond !!
Please someone tell me?
Very clear, but very slow
does anyone else agree with me when i say his arm movements on both views of him are really distracting??
@Tyler DeWitt Thank you so much for this video!! Perfect explanations, examples and models! It helps really to imagine what happens!
Good luck! 🙂
Thanks again for these videos, huge help, especvially for us who cannot afford college, who buy their textbooks online. I am now watching your videos for every section I have read in this textbook I got on ebay for 5 bucks.
what about the water molecule ; it consists of 2 things and should be 180 degree apart. right?
@Tyler DeWitt Hahaha….
you can do that too, ethane would be like two trigonal pyramidal structures connected head on.
kabushaha it would be bent
he has explained it .
I like your username
You are awesome!
Just 1 question about the shapes. Which atoms create.
Linear when two things 180°+180 °=360°
Trigonal when three things 120°+120°+120°=360°
atoms get tetrahydral in shapes when”4″ things come into play. So my question is why atoms doesn’t arrange themselves in a way that looks like square in shapes.
Like 90°+90°+90°+90°=360°
I’d very thankful if you can clear my concept cuz what I see is atom gathering together to form 360° in total so why tetrahydral in shape for 4 things. 109.5° leads us where
@Ans Ali Just get to basics, shared pair of electron wants to allign themselves in such a way, so they can be away from each other as much as possible. ( due to e-e repulsion)
In square shape , The total angle would be 90 degree , but as said above, to minimize repulsion, it want to get away as much as possible. so instead of 90 degree, it will prefer 109.5 degree thus forming tetrahydral shape.
and If you think about trigonal shape, it’s not because molecule have studied maths or it wants to look cool, infact . it is the the only possible shape where 3 shared pair of electron will be apart from each other to max. extent.
@Harman SINGH thanks for the help. Really appreciated.
tyler,
at 2:50 you say that “these electrons want to be as far away as possible”. which electrons were you talking about? was it the 2 electrons in each bond or the 2 bonds itself?
+Kevin George The electrons in one of the bonds repel those in the other bond. They are holding the Cl attached to them at 180 degrees because if the moved any farther up or any farther down they’d be closer to each other.
Do you teach Organic Chemistry???
Thank you so much for your helpful videos. I am so grateful for your tutorials, as I am currently taking a self-paced independent study course through BYU and only have my text as a guide. Honestly, I would be banging my head against the wall without this!! I have used Khan Academy in the past, but there seems to be a tendency for the instructors to ramble. Thanks again!!!
You’re amazing your videos are so easy to understand you help me understand everything for my final exam! Make more videos for chemistry !
Awesome explanation!! I’m kinda in love with your analogies cause’ I understood very well the way u taught in this video.. Thanks a bunch for such a hardwork.. God bless you dear.. 🙂
I love you! This video was amazing and so helpful. My learning process is enhanced by because you are so eloquent and handsome.
Many individuals who do chemistry tutorials could learn from you. You consistently give thorough explanations in each of your videos. It helps so much!
Nice illustrations.
You are so great! I can’t thank you enough for making your videos, all of my friends who are taking chem watch your videos also. You seriously help us more than you think, my professors take 2 hours to explain something you can explain in 20mins or less AND make it fun and interesting to learn. THANK YOU!
Forever thankful for your videos, and your dedication to share all your knowledge with us!
this is awesome just keep it up
The visual explanation using 3D structures of molecules helped a lot in understanding the concept very clearly.
Would someone explain for me to understand why VSEPR is important? Why we need to learn this? Forgive me if my question is stupid, but I am curious to know. Lol.
ahh..well..vsepr helps u lrn about the.. lone pair-bond pair repulsions which inturn helps u in undrstanding the way these atoms are arrainged in a molicule with respect to the repulsion series mentioned in vsepr…on one word..it helps u in figuring out the structure of molicules….thts it
All the bent shape molecule are 105~ degrees? Doesnt the electronegativity have an effect on it and if so why does it important to remember the degrees?
i love you!! great videos also very handsome tutor…..
thank you, your videos are great. please continue making videos on all chemistry subjects, especially ap chem @Tyler DeWitt
are the electrons always in pairs @Tyler DeWitt
Mr. DeWitt is so damn good in teaching! Like holy crap, I finally GET IT.
thanq so much Tyler
BeCl2? Is it really called beryllium dichloride? thats a combination of a metal and nonmetal, i think you don’t put prefix on it.
So Be is an exception and doesn’t follow the octet rule.
+mahnoor shahid ur right and remember AlCl3 too is covalent !!!
Abdul Moeiz Yeah well Al is definitely a metal
U r right but remember AlCl3 is both ionic and covalent as per Fajan’s rule.
Al3+ has (+)ve charge which will attract electron cloud towards it.
this will disturb shape of Cl3-. The electrons will come in axial line b/w
Al3+ Cl- which is character of covalent bond.So, it have both ionic and covalent character..
this is an ionic compound, shouldn’t be used as an example for a bond angle
Please do a vid on resonance; chemical bonding. If you already have one made, please reply with the link, I’d be grateful. Thanks!
This is pure fire.
got it nicely
+Tyler DeWitt Hey…….thanks for the video………enjoyed ur explanation and the concept
How do i memorise which atom has how many lone pairs? i watched every video and understood everything (Great Teaching methodology btw!), but that part always trips me. Is there some sort of trick? Thanks in advance 🙂
+jwalant bhatt You need to draw the Lewis structure of the molecule, that’s the easiest way to figure it out. Or consider this: the central atom, with the exception of Be and Al, should have an octet (8 electrons) around it. So subtract 2 for each bond it has, and the other electrons should be in lone pairs.
Oh gosh you’re sooo kind! I was actually planning on where to go next while it’s loading *^.^* and after that ending I realized I’ll be screwed XD Thank you so much! YOU DESERVE LOTSA LOVE!!
You’re doing great stuff,man!
Thank you! +Tyler DeWitt
why not u do the video about hybridization
Amazingg videos
You are the best teacher. My chemistry teacher in should be fired
that was jst amaizing….well explained….it jst saved my time..👍👍👍👍👍
why it is pronounced as VESPER when it is VSEPR?
thanks Tyler it is really helpful your explanation. it’s clear and accurate I like it. I was confused before now I have clue .
love this video!
good video homie
you’re truly one-of-a-kind
i love you
thank you sooo much
So would H2O be a linear shape? I always thought it was more like a triangle.
+David Madison no it has lone pairs
+David Madison No. H20 may seem like a linear shape but after drawing the lewis dot structure you realize that their are 2 lone pairs on the O atom therefore H2O will not be a linear since it does not have 2 ,but 4 bonds attached to the central atom ( which is Oxygen). H2O is bent
@ZC Z Thanks. I really appreciate the response.:-)
@Gabriel Jawiche thanks for your reply the description really helped me understand where I went wrong
Ok, guess at about 8:40 you addressed my H2O concern.
i love you so so so much… really… finally i understood
I have online chemistry and ALL of his videos help tremendously! Thanks Tyler!
In a covalent bond,there are 2 electrons from each atom.I want to know how these electrons live together in a bond having same negative charge?????
thank u so much ….because now only im very clear in VSEPR
Thank YOU!!! NOW I get it.
totally save my life. thank you so so much from the bottom of my heart.
Thanks Tyler 😊
My Chemistry instructor asked us to come up with a Lewis Structure for BH3 with LiH, anyone have any thoughts?
Thank you!
Your videos are phenomenal man. Thank you so much
Your videos are really helpful, can you make a video on how to draw lewis structures?
Tyler, Do you have ANY organic chemistry videos?
my question is i read in some book that the lone pair electron have long distance from shared pair why is that
bcz they take more space
What are the element exceptions to the octet rule?
+Jessica N
H, Li, Bi
+mary12497
I meant Be not Bi
+mary12497 Thank you!!!
Amazing
great video
please make a video on molecular orbital theory
bless your soul sir. i can finally understand this
1.5x speed anyone? Superb video tho
They should replace my textbook with your videos
@Jake Fields Good teacher! My textbook explains some things clearly and other…eh, I sometimes wonder if the author himself even understood the topic.
Very good licture
Totally agree with you
@Esej Snake Same! I couldn’t agree more lol
I learn more from the internet than from my teachers
I love your videos! Thank you!
Can u show the polarity plz?
Just DeWitt
Sara Faheem LMAO
LMAO
This should definitely be a shirt
+Jordin Levy so true
@rp hey…r’nt u the guy who struck up a really long(tho beautiful) conversation with cristopher?
Ur conversation really made my day☺️😊😉
(Others…just don’t mind me)
After watching this video. I wanna sue my teacher!
It is so sad that we have a big chapter on Chemical Bonding being done with in 6-8 classes. Is the goal just to get people in good colleges or to actually teach something which is very interesting ?
Great vid~!
Please make a video on the bonding continuum and polarity! 😄
superb effort
Thank you, Mr. Dewitt
wow great work you reallly helped me alot thank you
Usn’t BeCl2 an ionic compound? If so, why are you representing the Lewis structure of BeCl2 with covalent bonds?
lazi danga it’s a polar covalent bond, something in between
You are awesome Dr. DeWitt!!!
I love you
Please do a video on hybridization.
Rachael Daley hey hybridization is just a simple topic
Can u give ur no.
Yes… I also need it
@Hamdan Ahmed Yeah man, it’s been an year
Oh yes I need that please
thank you so much this is really helpful but i’ve got a question
do we have to know how to draw lewis structure in order to find the vsper ? cause i have a huge problem to find out the lewis structure
thank you 🙂
YOUR AWESOME!!!! Seriously I took my fist Chem class ever and totally rocked every exam thanks to u.
god bless your soul
Can tell the homeschooled kids of cult parents.
Hi exo l
Great job Tyler!
I love your videos. They’ve helped me a loottt!!
Can you do a video on Polarity and Hybridization? please!
Taylor can you please make more videos about AP Chemistry please
Like Hybridization 🙁 i dont get it at all
thank you very very very much kind sir,i bow down to you in gratitude.May god bless you and all those you care about thank you for the lectures,and please do keep making such videos
Amaaaaaaazing.u r a superb teacher
Not all heroes wear capes.
Some uses a whiteboard and a marker
Some wear lab coats
Some just talking
wtf nerd necck he said opposite charges do not repel
@OKCCanna Reviews .
I LOVE YOU MAN! ahaha seriously, thank you so much!!
nice
Wouldn’t the angles in the CH2O molecule technically be <120 and >120 because of the double bond between Carbon and Oxygen?
Yeah. Maybe he made a mistake? 🙂
Hello there, good video. But i want to ask how can we recognize whether the atom is “happy” or not if they dont reach the octet state. Meaning to say how are they excluded from the octet rule.
isn’t the structure of so2 this o=s=o ?
Vignesh R probably a year late but no. Oxygens need to have 8 electrons & how you wrote it they only have 4
make a vedio on valence bond theroy
Good teacher 😀
In BF³ there is tetrahedral shape, how ???? what about the electron pairs of ‘B’ ?? Because any atom performed Octet (expect H)
+Tyler DeWitt, could you make a video on hybridization and orbitals ?
I always thought I hated Chemistry until I realized it was all because of teacher! Now I can understand what we are learning about in class. Thanks Tyler!
P.S. Maybe I just missed it but do you have any videos on just Lewis Dot Structures?
SPEECHLESS. BEST CHEMISTRY TEACHER!!!! T.T T.T
Thanks a ton ! 👏
Did you say opposite charges repel?
+Bomb Just a mistake I guess.
The videos on VSEPR are excellent. Where did you get the models that you use ?
TonyPell
I hate mr Skarecki
Penis
thank you so much! you should be my chemistry teacher! 🙂
you gotta be my pen pal !!
umm what?
Fuckin creep XD
Thank you! This is a huge help!
These vids really help.👍👍👍
You’re actually a life saver
think you very much
May God bless you and reward your effort for helping us all out in this our moment of confusion.
Seriously ? Are you home schooled ? I think the teacher does this because the world will be better with fewer confused people. Why isn’t god blessing babies with cleft palettes, or children being sold into servitude. Is god just there to help you with exams ?
daniel letterman wtf are you saying stupid ? let him preach
@daniel letterman god is busy counting your mistakes, also counting your moms too
This was very helpful. Will be subscribing to your page for all my organic needs. Thanks 😊
God will definitely bless you for this. In a two hour lecture I couldn’t understand this and in this video along with the others, I have understood it completely. Thanks a lot.
@Another View maybe to you
@savethe Coconuts There’s no logical explanation for any of the countless Gods people have conjured up over the years.
u learn this in uni?
@Another View attack of the athiests
thanks men
Thank you, very well explained.
Ms. Hale crew representing
Perfect video! Thank you!!
At 1:41 he said that opposite charges repel. Like charges repel, opposite charges attract.
Excellent video! Thank you so much.
Can you do a tutorial on how you made your 3D molecule model?
Great….!
Thank you Sir..ji…
+saqlain sk. it is my farz… 😛
thank you .. no no thank you so so so so much. you helped us so much. i dont know why our inestructors not as easy as you
Super
1:39 Oops! “opposite charges repel”. s/b like charges repel.
the main reason i’m passing hon chem
the degrees is only really to help you with bent shapes right?
why dont you have any videos on how to draw lewis structures?
Britny Rivera may ik Which file it is under? Thanks
+Britny Rivera can you tell me where is it? i really need those. my teacher just told me and my friends to practice a lot but dont give us any useful tips and tricks to draw it. im stressed out. its really confusing for me.
that’s a very good one try it and let me know
Vanessa Mumu I couldn’t find them either. I prefer his method of teaching. I can’t believe he would just skip it. Maybe they’ve been deleted?
Why should he make a video like that? There is plenty of videos which explains how to draw Lewis dot structures.. He made this video to teach VSEPR a different way than others. He’s a good teacher =)
IN H2O THE ATOMS ARE NOT AS FAR AS POSSIBLE FROM EACH OTHER IN THE VIDEO WHY IS IT LIKE THAT
HATS OFF TED AWESOME OUTSTANDING VIDEO WITH GREAT EXPLANATION
THANKS BROTHER(TED) THIS VIDEO MADE ALL MY BOND ANGLE DOUBTS CLEARED..
Thank you very much!!!!!!
great!!!!
Umm.. Please Can You do a videos of hybridization cz im screwed in it 🙁
So this is the exact same thing as electron geometry? What about molecular geometry?
This video helped a lot. My professor made this way too confusing.
+Collegegirl45 Molecular geometry is the arrangement of the atoms, ie; bent, trigonal, tetrahedral…elcectron is the arrangement of the electrons on the central atom…
check this thing out, it’s a 3d representation of a few molecules, I found it to be super helpful.
we need you ,come back and make new videos please 🙂
Very, very, well said
I couldn’t understand this in 2 full hours of a lecture but I understood it within minutes of watching this video.
This is the most helpful video ever. Thank you so much.
Thumbs up if Mr.gaichus is the greatest chemistry teacher ever
Can you pleaaaaase make a video about properties of a hydrocarbon??
How do u tell if a molecule is trigonal planar or trigonal pyramidal
This video is amazing it helped me so much. I thought I was going to fail my chem test tomorrow but this has seriously helped me understand VSEPR so much better. THANK YOU!!
You are my favorite Chemistry teacher.
This guy is Damn good omg. I wonder how many lives he saved hahahas
Hahaha’s
He has helped me a lot he is really good at explaining and how I wish I could have a teacher like him in my country…thanks Tyler
count me in!
he does not save any lives you moron! he said opposite charges do not repel! ok Boomer! have a noicce Day!
@Email Email hey u ***************************** ************!!********?!?***🤬😡😠
Opposite charges obviously don’t repel
What’s wrong in that??❓❔❓
thank you
You are amazing.
thank’s fr ths video
Correction -Like charges repel each other.
Explained very well. Thank you:)
You are awsum. Can you please post the videos regarding VBT and MOT
Best Chemistry Teacher!
Can you please replace my Chem teacher 😂
you are bae
Your videos are fantastic! Wish I had you as a professor, thank you so much!
For SO2 wouldn’t you want the best Lewis structure?, anyway great video, helped me a lot.
Replace my chem teacher Sugimora!!!!
I am so glad that I found this video!! You are such an extra-ordinary, smart and eloquent teacher (instructor). You just make everything becomes so easy. I feel like i do not have to spend hours in chemistry classes to get the topic.
You are really helping me get a grasp on chemistry, thanks!!!
So the shapes that you discussed were only molecular shapes?
I just discovered your channel on this video 😀 and i am truly thankful; you need to be a professor at a university! Thank you for all your effort <3
Why unpaired electrons push more harder than bond atom to have bent shape?
please do video on hybridization. thanks
Thank you man.
very good videooo
You have saved my life. I am eternally grateful.
ahhhh!!!!! I wanted to know what this theory was for so long!!!!! thank you so much…!!!!! I understood everything..!! Looking forward to learning more chemistry from you…:)
this is realy awesome!!!!!!!
Great video, but why is Be an exception to the Octet rule? Why wouldn’t there be double bonds?
👌👌👌
Thank you, you gave me the “ahha” moment.
plz tell me that does this theory explain all kinds of bond or only covalent bond???
we’re talking about covalent bonds here
Goat
..this is really good. I must applaud you
I’ve never seen any video so amazing and so simple to understand like this video. Thankyou so much Mr. Tyler. – From the United Arab Emirates, Dubai
Don’t understand why SO2 share electrons like that……plz can someone explain?
damn, your explanation is so good
easy for me to understand
thankss
Thanks !!! Very Helpful !!!! Definately one of the best tutorials on YouTube !!
i have a doubt. in H2O , the central atom is O and there are 2 hydrogen atoms on either side , but it doesnot have angle which equals to 180 deg. . it is a bent molecule , but according to u , a molecule which shares electrons should have an angle equal to 180deg..
Nope H2O Has a Tetrahedron shape. H2O, The valence is: 2H=2, O=6. the are 8 bonds in total H•—-• _ö_ •—-•H with 140 degres H angles
got the answer , i didnt watch the whole video
HI BRO CAN U PLZ UPLOAD THE LECTURE OF MOLICULAR ORBITAL THEORY AND PLZ TEACH US THAT THERE IS ANY FORMULA FOR CALCULATE THE DI POLEMOMENT AND THERE IS ANY FORMULA FOR CALCULATE THE BOND LENGHT
I can definitely tell that you take teaching very seriously because you are very patient at explaining things. I am very grateful, thank you for this video!
20:27-28 you said 180, but I think you meant 120
Nice video! Thanks 🙂
You’re the man, thank you! The speed of your speech and the way you explain concepts makes learning far more enjoyable than in the classroom. Cheers!
I spent an entire year on this crap and he just taught me in 20 minutes. godbless
omg i love u im currently crying as i type this thank you so much you saved my life
Bless your soul. I’ve been studying this for a year and I’m only starting to get it
Can you make video of Covalent bOnd
Cramming for my Chem final tommorow. Tyler is making things so much clearer than my teacher has taught for the past 8 months!
Exams coming up and throughout the year I’ve a few of my study notes. Thanks for making this!
I have Chem final tomorrow. trust me I’m a dumbass and I learned the whole course from this channel.
you must go for hybridization now as soon as possible…….
Can you make a video to differentiate voltaic, electrolytic, and galvanic cell ? Thank you <3
thankyou very much sir ! now finally am able to do this…
AMAZING
Bless your soul mate, this video showed a more proper explanation that my chem prof
This video really made my life easier. ThankYou Sir. You are awesome.
Tyler Dewitt saved my life, I now finally understand what my teacher was trying to teach
Thank you so much! My chemistry textbook confused me so much on this topic.
thank you so much for this <3
best chemistry based videos on youtube…love from india
Very nice video! Great efforts taken!
thank you!! I couldn’t get till i watched this !
great introduction
I loved this video
what about h2o?
Thanks for this useful Lectures!!😉
According to the cloud model of atom, The H2O should be a Tetrahedron instead of bent shape
kr3wdog06 correct! Guys, remember electron geometry takes into account the bonded and non bonded pairs Molecular geometry takes into account ONLY the bonded electrons. That’s why water has an electron geometry of tetrahedral because of the 4 electron domains, but because it only has two bonded electron domains, it’s bent.
with lattice formation and crystallisation the the geometry changes…that’s true….well chhavi Gupta… can u please contact me in fb….it is 9830738118..I have the same profile pic
Aryama Chatterjee check out ur ‘hangouts’…I messaged.
Geometry of H2O molecule is terahderal, but shape of molecule Bent because Central atom Oxygen contains 2 lone pairs and two bond pairs.
Pooja Kumari no, the electron geometry is tetrahedral. the molecular geometry is bent/v shape. I’m not sure why you feel like commenting on something that has already been correctly explained..
SO2 has 3 pairs electron, therefore, it is a planer Triangle. In the case of SO2, these 3 pairs of electron form a resonance bond. Draw the planer triangle shape, place S inside the triangle and then put the O______ O outside. You should have a distorted 120 degrees
THank you for the video! It was really helpful!!
Thank you – you explained it so well!! You are a great teacher!!
what a champ
how come I dont see anyone excited saying “hey… my homework brought me here”?
HOLY CRAP THIS IS THE MOST HELPFUL VIDEO I HAVE EVER SEEN IN MY LIFE. THANK YOU I GET IT ALL NOW 🙂
YOU ARE A GENIUS THANKYOU! YOU SAVED MY LIFE #ibchemistry
did he said “opposite charges repel”?? at 1:38
read the annotation, he meant like charges repel
Give him a break, hes out making life saving videos for you guys and all you wanna do is make him sorry for a really teensy minor mistake that you already know the correction.
Awesome!!!
is this just me or his hand really is animated
thanks a lot for this vid…
Thank you so much for this video, it helped me a lot!!
Opposite charges repel?
He got a annotation saying he said it wrong .-.
SO2 should have two double bonds, I believe.
Thankyou so much!! Explained well
would you please mind making video in pie and sigma bond..😁😁😁😁
I dont think you made a video explaining Lewis structure.
Watch bozeman science videos, he is also pretty good.
Why did he said that Boron has 6 valence electron? Someone?
He other two are shared?
Oh he said it’s an exception to the octet rule
ohh ok thanks
Beryllium gets 4 btw
how to know what atom is the central one?
The less electronegative atom will be the central atom (:
+Emma Wxtson i just lowkey admit that I like to imagine you’re THE emma watson and i get so excited about it. So don’t ruin it. Thanks emma watson. That made me so horny 😂
+Emma Wxtson thank you!! I was thinking the same question and you answered it, THANKS!
thnkssss guysss, tomorrow is my final. oh plis pray for me
Best Explanation! Thankyou Very Much Sir!
Can you please make a video on hybridization?
it was worth a watch truly
what if it has a James bond?
Lmaooo
than the atomic no would be 007
It’d be taken, not shared.
This is a good joke i applaud you!
why
Thank you for being one of the fewest teachers that make me feel like science is such an awesome thing to learn
S
by far the best explanation for VSEPR. Thank you sir!
You are a really good teacher and you saved my life. I had almost zero foundation in chemistry and was feeling hopeless about my chemistry exam in Nov until I watched this video. Thanks so muchhh for making this video!!
Best efforts
thanks this video helped me a lot in my reporting tommorow 🙂
from which country do u belong and very very thanks for these videoes
Hello… I could not find the answer to the question about why considering BeCl2 as a covalent compound… I’ve always seen metal + non metal compounds as ionic…
you are so awesome youre saving my fucking life man
wow thank youu
Omg man, thanks!
– a M.Sc. Chemical and Energy Engineering student in the need of this!
Thank you so very much for this video, it was a godsend after my complete retentive disaster in recitation this morning. I have to say this again, thank you because I don’t think it would be possible for me to thank you enough.
Oh, almost forgot *smashes subscribe and le like button*
two lone pairs(h2O) have 104°5…
Great Video Sir.
This helped a lot! Thank you so much 😊👍🏻
Kudos to you, sir. I don’t need my Phys. Science teacher anymore
amazing explanation
God bless Tyler Dewitt. He saving my grade.
Cant save my spelling apparently rofl
Thank you so much. I really appreciate what you do
that’s all great and knowledgeable video thanx for giving it
Tyler my man, you are a good person
If it was in HD then it would be 100% perfect
You accidentally said “opposite charges repel” @ 1:40 🙂
That moment when you search YouTube for a chem topic you’re studying and see that Tyler DeWitt did a video on it 😀
made my day
it is not the opp charges repell it is same charges that repell
YO THIS VIDEO HELPED ME SO MUCH YOU ARE SO HELPFUL please dont stop making videos. ive learned so much within the first 10 minutes than an hour worth of video lecture notes… that are not even made by my professor.
thank you so much!!!!!!
Could you explain how in SO2 the oxygen has an electron to share with sulfur when you drew 6 dots? Oxygen only has 6 electrons in its valence.
Tyler DeWitt for President!!!!!
Amazing!!! Thank you
Fantastic sir
My chemistry savior <3
thanks man you are great and so clever , you are explaining the lessons smoothly in a great way go ahead
If anyone can help, I am more interested in the atoms, neutrons, and protons that make the elements. What career field should I join? For instance, creating new elements? Is it nuclear chemistry or nuclear physics, or perhaps something else?
The goal I feel inclined to is rearranging of atoms to take the protons or neutrons from one and create another.
Anyone else notice he said opposite charges repel ‘
Rajneel Narayan Thank god i found your comment, i thought that no one realised this after *5* years!
Yeah xD
me too..confused me as heck!
He meant “Negative charges repel”. Electrons are Negative charges.
@SkillUp Gaming yes,u r right…
isnt there an octahedral?
He has another video about octahedral bonds.
THIS GUY IS AMAZING THANK YOU MAN
Wilfred Ikej can some one please explain to me why the cl and cl electrons try to go away from each other but not the cl and Be electron go away from each other i mean how could they even join together if electrons have same charge at 4:00 please some one explain to me it might be the most stupid question ever but i never focus in class or study at my own so…
I wish you were my professor…. Make life so much easier
You are really good in explaining chemistry 😉 I can understand you without any problems although my native language is not English 🙂
Thank you so much
How do we Recognize the lone pair in a molecule???
It’s when the valence electrons of the central atom aren’t covalently bonded to the electron in another atom
HighschoolChemistry # thank you so much. Must appreciated your help😊😊😊
Thank you so much, my exam is Tuesday and this has been so helpful!
Thanks for this awesome video. It made me understand VSEPR more. 🙂
Thank You!..I love you professor!..How can I give you my hug?.
You are a life saver. Thanks.
Thanks so much this really helped!
At 7:39 you said it’s going to be have an angle of hundred and eighty degrees? when it’s a trigonal planer and should. have 120 degrees angle
It wasn’t intentional
He said 120 at first
thank You 🙂
You really helped me sooooo much.
i wish you were my chemistry teacher
You are my go-to chem video help master dude. I love you so much please keep making videos you explain things SO clearly and the models really help
Thank you so much!!! This has been amazingly helpful!! I appreciate you and the work you do and share with us.
this channel, this video is this teacher all of these are amazing …
Thanks I appreciate it
I didn’t even know that I’ve watched a 20 min video
i understand fooooo
writing chem tomorrow, thanks to you probably acing it ….THNKU:)
why is SiO2 not linear shaped?
@Aryama Chatterjee sir, I had an examination, and there was a question…which of the following has a linear geometry? The options had both CO2 and SiO2. To my utmost surprise, SiO2 was incorrect. I’m still not fully sure about the reasons, so I’m trying. Now ahead of this, I consider myself unqualified and knowledge-defficient to be able to argue further. And surely, this 9th grader is incapable of providing u with the best explanation. So let’s just hope that our teachers will clear our doubts (if u have any regarding this topic, bcuz I surely do have). Thankyou!
+Chhavi Gupta you are most welcome please do get in contact with me in fb..it is 9830738118..I am there with the same profile pic
+Aryama Chatterjee hey, I’m sorry for replying late. honestly, I didn’t know what to reply…it’d be good to get in contact. but the strange thing is I’m not on fb. (I know that’s primitive) :-/
SiO2 has linear molecular shape. The two O’s each double-bond covalently to the Si, leaving no electron pairs attached to the Si (the central atom). With no lone pairs to interfere, the two double bonds push as far as possible away from each other, creating 180 degree bond angles – a line. CO2 has the same molecular structure as this, for the same reason. Pi electron is not included in the ACTIVE SET OF ELECTRONS. O = Si = O
Linear would be correct if there were only 2O atoms and a single Si atom, however, SiO2 forms a network solid. This causes the double bonds from O with Si to be turned into single bonds. As it is a network solid, the Si atom will be surrounded by 4O atoms with single bonds each. This shape is also known as a tetrahedral and a tetrahedral has bond angles of 109.5 degrees, 110 degrees for simplicity.
….O Si O Si O Si
O-Si-O-Si-O-Si-O
….O Si O Si O Si

I want to marry this guy.
Should SO2 Have two double bonds to get a formal charge of zero?
What about bent vs linear? Lost me 5% of my grade on an online assignment, give me my + back
Chemisnate is better
please I need you to go through NMR spectroscopy
14:20 lmao the angles under the trigonal pyramidal look like a face with a red nose
I was having such a hard time with VSEPR and Lewis Dots. Your video simplified the topic so well! Please make more videos! 😀 *particularly on organic/inorganic chem ._.*
9:27 the lone pair electrons look so cute…i dont know where that came from, just feels cute….
so, for the electron geometry we dont take the lone pairs intro consideration, but for molecular geometry we do?
I have a chem H test on Wednesday…I really hope this helps
Seriously, you need to be my lecturer. You are wayyyy better than my lecturer.
Jennifer Stefannie too
Hello Mister Tyler DeWitt. Congradulations for your videos! Can you please tell me if you have any video explaning how to do the Lewis Structure? I searched but i could’nt find any…thank you very much, and once again congradulations!
Thank you.
this videos about VSEPR are the best!! you helped me so so much!!
thank you 🙂
I dont understand how Be can be covalently bonded with Cl. Isnt it an ionic bond? and when covalently bonded, doesn’t the outer shell of Be still have only 4 electrons? so it’s valency is still not fulfilled??
God
Thank You!! You are a lifesaver!!!
You are really helpful! I understand much better than I learned from my class. The structure/picture was really helpful while explaining it. And also, you explain in very detail, professor usually skipped it and make it very hard to understand..:)
So, why does barium dichloride have single bonds while carbon dioxide have double bonds?
Clay Harrell because barium is happy with 4 valence electrons while carbon needs 8 valence electrons, elements follow the octet rule.

Best Chem guy
Tyler sir is a gift from Jesus to all chemistry students. he teaches soooooo well that it cannot be expressed through words.
Superb
thanks a lot
🙂
Thank you! It’s really easy to understand! A big thumb up for you man!
I have a question, what is the central atom of the O2 and what its shape?
Asmaâ Aldosari *facepalm* O2 doesn’t have a shape due to it is only 2 atoms bonding.
znar swar So VSEPR is only for molecules that have 3 atoms and so on ? I mean more than 2 atoms ?
well look, what are the possibilities of arranging two atoms in 3d? there’s always only ONE way – line
amzy .yzma But the O atom has 2 pairs of inshared electrons , doesn’t it ? shalln’t we define them as 2 bonds ? plus the bond with the another O , so ?
you’re a good teacher 🙂
I love this guy bc I learned a lot but his swallows got me rotfl 😂😂😂
i noticed that too lol.
Lol, what you mean
OOOMMMMMGGGGGGGGGGGGGGGG
YYYEEEEEESSSSSSSSSSS
Mr. DeWitt, have you done any videos on hybridization, or covered that topic in any videos?
does it bother anyone else how much he uses his hands?
ghadeer bader what do you want him to use his feet?!
ليتك ساكته
u just got rekt
His hands does not constitute any problem to the teaching but your senses that pay attention to his hands only is a problem to you. You have a big learning problem.
Geez that’s kinda rude..
bent is 104.5 not 116
+ghadeer bader The video is correct.
great vid man, so informational! Thanks
That moment this guy is more of your chemistry teacher than the one you see in school every other day…
Tatianna Carrion buss down tatianna
I have a test on VSEPR tomorrow and I didn’t understand at all until I watched this video, thank youuu!
Sir why you are not making videos for organic chemistry i.e. about carbon compounds???? We really need it. Hope you will look for this..
you’re so adorable and I love your videos. Thank you for getting me through college chemistry <3
is it only me but does he sound a lot like the actor who plays Dr. Reid on Criminal Minds?
Amazing Video, I have learned alot, you changed the way i think about chemistry thank you tyler!!!
really you ar the best chemistry prof i have ever seen > big great to u from egypt
Thank you so much.
I love the edit of the video. well done 🙂
Upload a video on bond and molecular polarity.
THANK YOU SO MUCH
great video really really!!!
You are helping me teach chemistry for the first time more than you’ll ever know! Thank you!
8:43 doesn’t “S” have 6 valence Electrons instead of 5 I am confused???
S can have different valency… You will understand it when you will learn co valency..from that concept you will get to know that after 2 nd period around every element has variable valency… It depends on how much you excite an atom..like cl can have valency 1 or 2 or 3 or 4…7 …depending on how much u excite it..
Can you please help me to understand why bond angle in water molecule is comparatively higher than bond angle in H2S molecule?
I hate youuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu
the MO theory, please upload that video.
What I don’t understand is why is it 116′ if the lone pair should only decrease bond angle by 2.5′ so wouldn’t it be 117.5′ or does it not really matter as it is just approx 116′?
Thanks!
Battlefield 3 ftw
the given video will also be helpful for chemistry lover
please be my teacher 😭😵
need a roults law
I need roult law full explanation+matimaticall
Very well-explained, THANKS YOU.
When he brought out the drawing of the bent shaped molecule I kind of lost it. I say a really happy face with a mustache
thank you
thanks so much. this really helped me
use background music
This is fake news
I swear to God, if you go to hell in the after life I will trade my soul for yours and let you live in heaven. God bless you.
Dude, you’re awesome! This is so clearly explained.
Great Video!!!
During my lecture, all I could think about was how I’d watch your videos instead to better understand the content. Thank you so so so much. I will pass chemistry mainly because YOU have helped me understand better. I am a visual learner, and I absolutely love how you incorporate pictures, models, mnemonics, ect. into your videos to make things simpler, and better to be understood. You have made such a difference in the way I study and learn. THANK YOU SO MUCH!
There is something wrong with the example for bent
Thank you!!!! This helped so much. Really great teaching.
Bless you literally for saving my life 2 weeks in school yet I didn’t understand and just by watching one of ur videos explained everything ❤️
You meant like charges repel, though you said opposite.
nyc videos bro
So simple and I could understand
life saviour
most excellent and simple videos:)
I found brain cells in a hopeless place.
I found knowledge in a hoppeeless placceee
God where have u been all my life thanks a lot I wish you were my teacher @ school i would not stop looking @ you
good
I don’t get why the lone electron pairs are so close to each other in bent shape? I mean isn’t VSEPR theory about repulsion of electrons so why aren’t lone pairs have angles between them too?
Wu
lol ur hands are funny
do videos on resonance structures and hybridization!!!!
Or do the triple bonds or double bonds
You’re amazing!
tomorrow is my finals. thanks a ton sir.
Hi Tyler, I just wanted to say thank you. I am doing fairly well in my Chemistry class mostly because of your approach in explaining the materail. My teacher teaches us the powerpoint slides but that doesn’t help us out much as we try to fully understand what is going on. I truly appreciate all the material you help us understand. Thanks again!
SLAY ME.
I HAVE MY CHEM FINAL TOMORROW AH
TYLER YOU ARE AWESOME (****) I love the way how you use models to explain things> I wish my professor teach this way. You are incredible and a great teacher and you should be awarded the best teacher of the year
do hybridization please
THANK YOU!!! Thank you, thank you, kind sir!!! You are a Godsend!
Could not explain any better, thank you !
im impress u
super cool! thank you!
Thank you for sharing, it’s so clear now. It’s hard to someyimes image how shapes are affected, especially the lone pairs. I went to my fridge and got grapes and anything speherical just to follow along. Thank youuuuu!!!!!!!!
you’re so smart.
you litterally saved my life.
This IS the best video on this subject, and I´ve watched dozens
one word: WOW! thanks!!!!
thx man the vedio is really helpful
In SO2 molecule two electrons can’t be so close to each other because of repelling force between them.
Hi Tyler,
it’s been years since I’ve been in school and not to mention English is my second language and chemistry third lol. I am back in school and your videos are helping me to get by and understand the chemistry as I never did before even in my own language.You are amazing and I can’t even express my gratitude for the work you do. I always hated chemistry because I couldn’t understand it but in your videos it is much easier and even fun. Wish you all the best and thank you for all you do. No videos out there are better for me than yours.
I CANT THANK YOU ENOUGH. ALL OF THIS MADE SENSE FOR THE FIRST TIME.. and i actually UNDERSTanddd this now… keep making videos to help us … and thanks once again 🙂
This was incredibly useful. Thank you!
Thank you!
i just wanna say god bless your fucking soul
Please do a video on how you became my chemistry professor 🙂
This was explained so well thank you!!!
I just don’t know how to thank you…… no words… love u and ur teaching…
You are the best !
Omg Tyler I love you . You made this so easy to understand . My professor was trying to explain this and he was just horrible. Thank you so much I understand chemistry much better because of you. Can you make a video on how to identify if you have a polar or non polar molecule please I’m having trouble with identifying one with a given element or geometric shape. Thank you
He said “Beryllium DIchloride” but Be and Cl is an ionic compound meaning that the “DI” does not apply in this case. Am I the only one who noticed that mistake on his part??
+Jeffrey Abarca You made a good catch, but it’s not a mistake. You’re right, usually metal and nonmetal makes an ionic compound, but BeCl2 is covalent. You’d think it should be ionic, but it’s covalent.
why isn’t the “trigonal pyramidal shape” considered “bent” like the others with an unshared e- pair?
You saved me all throughout my first semester of college chemistry and I just want to thank you for being a God
Very good presentation.
I swear I have been stressing for days on youtube trying to understand this. God brought me an angel named Tyler. Thank you so much!
MORE THAN THAT! lol
this is a great video.but during the video you told, “opposite charges are repel each other”.i think that’s wrong
I love you tyler. I say it in every video I watch of yours. Your teaching style is truly amazing and I understand everything so well from you! <3 Forever grateful for you helping me and so many others pass chem!!
You look like a blonde Brandon Urie. 10/10
You truly have a gift for teaching. Your videos are so clear thank you! God bless you!
God bless everyone xx
why can’t my teacher teach like this, thank you!
You are the best! I looked at other chemistry videos and can’t stay focused, but yours are just amazing! Keep up the good work!
You’re not explaining what determines the shape, though.
VSEPR says “valence shell electron pair repulsion” so if there is a double bond so there are 2 pairs of valence shell electrons so they will also want to stay as far from each other as possible, according to VSEPR………
WHY ISN’T THAT??
goat
Hi Tyler! I just wanted to give you a HUGE thanks- watching your videos this semester is why I not only passed my basic Chem course but got an A. You are an AMAZING teacher. Thank you SO MUCH!
WHY DIDN’T I FIND YOU SOONER
vry nice vdo its really vry helping
should be paying my tuition to Tyler because these videos are how I learned chem. thanks.
Hey Tyler I wanna how do we find the center atom of an molecule
There’s something super special about your teaching. And I’m beyond thankful for you for sharing that. I have trouble concentrating on lectures in class, but your videos have helped me. God bless you, sir!
Not only do I love the way u explain things in a way I can actually understand and follow, I love the way u also tell us where to go from this video so I’m not here wondering which video I should watch first. THANK U♥️♥️♥️😭😭
Shouldn’t Sulfur Dioxide have a double bond on each side? O=S=O? Sulfur should have six valence electrons, he has 5. On the left side his oxygen has seven but should have six.
best vedio i loved it thanx a lot.. 🙂
Thank you very much
its obvious that you love chemistry
Wait… I’m even more confused now. He said it didn’t matter if there are double bonds or triple bonds- it still counts as one thing around central atom. But then he goes on to count a double bond as two things? I pray someone replies before tomorrow. omg.
Tarryn Nell I don’t think I ever count a double bond as two things. Where do I do this?
Thank you for responding! I could be misunderstanding, sorry!
It’s at 8:12. I’m not sure if I’m just completely missing the plot or what…
Tyler DeWitt I watched it over and over and I understand where I misunderstood. The two electrons above the S count as the third. I thought you were saying that the double bond with the O counted as two things. But now I see you just counted it as a second thing.
Tyler DeWitt If that comment made no sense… don’t worry about it. I’ve got it 😂 thanks! You’ve helped me so much. I’m definitely going to subscribe!.
this video is helpful but why is the bent molecule’s angle 116? in my book it says 105
where can u go to get an explanation of chemistry without saying the particles want this and feel that?
please do a lecture on hybridization too i desperately need it
thank you so much
thxxxxx
How do i donate?
Indredible
Your videos are a life saver ! Thanks
Why dont the pairs which are a part of the double bond try to go as far away from each other too?
Boron Difluoride: BFF
you’re a genius..
Damnnn,!!who unliked this video should be ionised,jk!
This was great for molecule geometry but I’m still confused and polar and non polar molecules
1:41
Opposite charges repel? But don’t all electrons have the same negative charge.
Thank you for this video!!
i was worried but your always there to help out thank you
Hell yeah boiii… gr8 teaching
Sir thank you for this great video, it helped me a lot in my exams.
very nice
Thank you so much for this video! Its amazing !!!
Whoa, you never made my expectations fail! I’ve been looking a video for my tomorrow’s lecture and this made me happy. Thanks!
You are the best teacher
please share the video on hybridization.
If they ask me in school who’s your chem teacher, I will say Tyler DeWitt
Tylor Dewitt please help me about the koulrasch theory
You save my life!
Thanks a lot
7:50 ”180° between each…”
a slight slip of tongue
YOU ARE AMAZING…JUST CHECKED OUT HIS WEBSITE!!!! OOOMMMGG!!!!!! I FINALLY SEE A LIGHT….Thank you so much! Please, please, please, don’t stop producing videos…..you’re like our saviour! <3. xoxoxoxoxoxoxoxo
Man ur awesome thanks bro it helped a lot
Vsepr theory in tamil
thank you for making me understand this total mess ♥♥
THANK YOU SO MUCH. I literally felt my stress level reduce more and more the further I watched this video for
U r a saviour!!!
i luv your explanation prof..
Thx BRO U Just saved my life
watching your videos make me question why i still need a high school chem teacher… :’) thank you!
Today I was listening to the TED radio hour from NPR and I recognized your voice on the episode of learning and education, THANK YOU SO MUCH for all of the videos!!
omg..you are amazing sir….even better thn my chemistry teacher… well done
But in double bond and triple bond, when there are 4 to 6 electrons held at the same place, won’t these electrons repel each other, the same way how the two electron pairs repel each other???
Bent structures like SO2 have bond angles of more like 119.5 degrees according to J.D. Lee and N.C.E.R.T. Beautifully taught btw.
Great explanation, Tyler,
1.36
Tyler- opposite charges repell.
Me – u r wrong
Finallyyyyy smeone proooved #thetylerdewitt wrong😎
Am a legend✌…
well we can’t compare his wrongs to yours because its infinite
👏Give 👏this 👏hero 👏a 👏Nobel 👏Prize!👏
Thank you very much for your helping to make it easier
Are you god gifted or something like that
But BeCl2 is ionic not covalent
OMG Im at the end and i cried when you said you have a practice problem video youre so helpful
amazing explanation
In SO2 , there’s a coordinate bond and a double bond I guess…
1:40 “Like” charges repel. Opposite attract
TYSM NOT ALL HEROES WEAR CAPES..
quick question tho. my problem is how you know which one is facing you and which one isn’t because you have to shade the triangular “wedge” now and its SO ugh! someone please help…
u r superb, ur teacher felt very happy after having a student like u. u r doing a grt job

@10:34 why does the electron pushes the other bonds a little harder?
sir when are u posting videos on valance bond theory and molecular orbital theory…
Please take hybridisation topic
I will pay to put you in in an air bnb to tutor me all semester here in LA.
Awesome video, thanks to people like you (those who make these videos) I do well in my courses. You definitely are contributing a lot to society!
Thank yoyuuuuuuuuuuuu!
GOD BLESS OMG
Life saver 🙂
I’m currently taking a degree in Chemistry in college. I always watch your videos whenever I don’t understand my Chem professors’ lecture discussions in class. Thank you so much for helping me learn.
Thank you sir.you are amazing.you make it understand so well
your 180 degree rule doesn’t work for H2O. Its central atom has 2 bonds but water is not linear.
When Tyler says 4 things around a molecule is that synonymous with the steric number?, ie does 4 “things” = steric number of 4?
Thank u sir. It’s really good. easy to understand
Sir , can u do vedio on hybridisation
Sir we need u come back plzz
U are graet
U are great
I m from India
N really thnkul to u
U r such a hard-working man
N cool man too
Thanks a lot for ur great n best efforts
This guy has endless ways of explaining videos so easily. I am always here when I don’t understand things!
thank you ily
can u do video on biology, please
It’s awsome………
Thumbs up if you could literally shed tears of joy because you finally understand.
This guy should be my Chemistry teacher
I’m going to end up owing half my degree to this guy lmao
Again, the almighty Tyler Dewitt has saved my ass!!
you are amazing. My professor is good, but I have a hard time understanding the material in lecture. you make things so much easier.
thank you for existing
This is amazing! I actually understand! You keep working miracles!!!
Tyler’s helped me so much through high school and now he’s helping me through university. I love you so much Tyler THANK YOU!
Amazing videos , you just have this zest to explain one of the hardest subjects in such a way that everyone easily understands. Keep it up and Please make some A-Levels Chemistry videos
For more video lectures on Vsepr Theory visit :
http://www.fahadsacademy.com….
It’s an unbelievably clear lecture ! Thank you sooooooo much !
Plz upload more videos.. especially on quantum numbers, thermodynamics, kinetics
how do you know if an element follows the octet rule? are there parameters? is it only a select few elements??
Please do a video on hybridization and save us…Waiting on u Tyler
Chemistry seems so much more approachable when you explain it. Could you please make a video about hybridization? 🙂 I’m sure many of us would appreciate it.
Why are the atoms pushed closer because of the lone pair of electrons?
There must be a reason right? Could you answer? I’m in high school right now.
I first came to you in Grade Ten. Now I come again in Grade 12.😂
At 1:45 you said “opposite charges repel each other”
The link for the video does not show
nice l can understand more in this video thank you😊😊😊
GREAT!
U just nailed it…………….
1:38 “opposite charges repel” – +
i just learnt this entire theory plus how to write lewis structures all in one EXTREMELY helpful video, could never wrap my head around it until this thank you so much 😀
God bless u
can you make a video on hybridization please?
Can I ask why on SO2? The left oxygen had 7, the S had 5 and the right had 6? Does it not correlate to its valence electrons?
I love u
Thank you so helpful!
Totally lovin’ you Mr. DeWitt 😘
i agreee i got so much respect for this guy, i dont even need to go to chemistry now
love it love you tyler save me everytime
Please do a video on sigma and pi bonds
YOU R JUST AMAZING . NO ONE CAN TEACH LIKE U . THANKS FOR YOUR VIDEOS
Thanks a lot .. this video is very useful for me to my last night before exam.
Umm…at 1:39 you said ‘opposite charges repel’ instead of ‘like charges repel’…
Btw…ur video was Awesome…People like u are a lifesaver for students….Keep making such videos!
Why did the chemist named Adam change his name..?
Oh..
please plz make a vdo on hybridization I really need it plz
Won’t the lone pairs on Oxygen affect the geometry of CH2O
Tyler you inspired me to start my Chemistry/Calculus/Physics Tutoring channel! Please check my stuff out guys
Me:”No animations
No colors…I won’t understand nothing…..”
Also me: ((wins nobel prize for highest grades in science)) 😂😂
why is double bond considered as one though it has four shared electrons else then one.
I love you 😍😘
SO HELPFUL
What about pentagonal bi-pyramidal structures?
dude your a life saver thank you 😀
Thank you for providing an extremely concise explanation. Although there are plenty of phenomenal teachers, there are far too many who use excessive jargon and rush through material without explaining it fully. You demonstrate a unique teaching style by explaining and then elaborating upon or re-explaining things that many teachers would explain once and then move on from, assuming that the student has fully understood and retained the material. I’m glad to see that your channel is doing well so that students like me can benefit from your videos! 🙂
really good video clears up alot
You are too good.
anyone on 2017?????
At 8:34, why can’t sulfur just make two double bonds with the Oxygen? That way, both elements can have a full shell full of bonded, shared electrons. Anyone get me..?
Thank you!🙂 Now I finally understand this!
Nice explanation thankyou sir
Allah bless you
You’re a blessing !
a handsome nerd
Tyler Durten
oh wait Dwitt
I love him. Very helpful for my acc chemistry class.
Well thank u so so much I have a chemistry exam and u helped a LOT 💚💚💚
EXCELLENT EXPLANATION THANK YOU KEEP IT UP
You’ve taught me in 20 minutes what my chem professor couldn’t explain in three lectures. Thank you!
7:54 do you mean 120 degrees and not 180 degrees?
Plz do hybridization
very nice
Based on a molecules shape, how do I determine whether it is non-polar or polar?
I’m eternally grateful for this! Thank you.
Subscribed!
How do you know if an element is an exception to the octet rule?
your the reason i survived chem!
Please be my professor, lol.
AWESOME THINGS ARE SO CLEAR
your videos really help me a lot,,,you make it look easy…thank you so much
well explained and will you please do a video about hybridization.
You make me a better teacher.
thank you very much
WE miss u please make more videos 🙁
Love U bro… Just U made me Love Chemistry ….it was my biggest enemy 😊
this dude is a master
hi your so good in discussing 🙂
Tyler this video is great but I noticed an issue at the end. The two lone electron pairs are put at 90 degrees apart from each other which maximizes repulsions. From my understanding, it would be better to put them on the same plane. So instead of having one on the north pole (top) and one on the equator (side) it should instead have both of them on the equator (sides.) If anyone has any information that contradicts me please present it, because my knowledge is still tenuous in nature but that was one of the main takeaways from the 4 hours of lecture yesterday.
Every time I watch his videos, I’m so amazed at how well he can explain things! Very talented, smart, and organized, thank you for constantly saving my ass in Chemistry you’re a genius!
but doesn’t boron have 5 electrons ? where is the other one when its bonding with the last fluorine ?
Can you show a structural formula please and is the ? Lewis formula the same as structural formula
Super
Penn State behrend Chem final tomorrow anyone?
I dont get it. Berillium chloride has an ionic bonding. so why do they share electrons?
Make a video on organic chemistry please!!!❤😭😭
calm down nerd necc
Somebody needs to give this guy a Nobel Prize for Best Teacher
Maya Papaya he didn’t create anything
@Liam Does Everything L.D.E doesnt matter whether he created or not he deserves nobel prie
There’s no noble prize for teaching you moron.
@Ashley Jr well then they better start giving off best teacher Nobel prize bcoz this guy deserves it
yeah
Why isn’t H2O linear
you are a good man
Thankyou so much i have chemistry exam tomorrow and i didn’t even touch my book ….just watching your videos to revise
Some heroes don’t wear capes.
Superb. Man…
In Becl2 lone pair
i would fail my final if it wasn’t for you
Good bless you…Very heard work
I got a 66 percent because of you
*same charges repel
Wow, you saved my life again. (^_^)
Hi . Im ur fan frome YEMEN
Wich all the best for u
And i understand frome u more than my D.r 😂😂😂😂😂💜
Tnx a loooot
Cool
Good vid. However at the start you say opposite charges repel. But it’s the same charges that repel. I know it’s a minor error but I couldn’t help point out😂.
bless this guy
Thank you so much
You saved me. God bless you
U make it much easier i solute u sir .thnkyou soo muchh😍😍😍
Be Cl2 is not Beryllium dichloride 0:44. It’s just read as Beryllium chloride. 🙁
Legend
wohooooooooooooooooooooooooooooooooooo applause
I agree he deserves so much I understand this much more better KEEP UP THE GOOD WORK AND WISH U A SUCCESSFUL YOUTUBE CAREER
Do a video on polarity of molecules please!!!
Unbelievable!! just a single word excellent!!
Lulu
Thank You…it cleared my confusions on 3d structures of the molecules…!!
Why you don’t have a video on how to determine Lewis structure?
can you explain us about hybridisation please
16:10 Adam, Adam, and Adam and Adam. sometimes i wonder who adam is… ):
This guy deserves a Nobel!
How do one know which elements are exceptions to octet rule?
Hey man!!!!!!! Your videos are out of the world. God bless you 100 million times. Thanks a lot.
dude your hands are wierdly long
waw Sir aaj today my all confusion have solved lots of thanks for this vedio
waw Sir today my all confusion have solved by you so lots of thanks for this vedio
Maan thanks a billion! I have a stupid teacher and i learn all from your videos.. Thanks!!
This guy makes me completely understand like. Thank god people like this exist.
Hy, Tyler! I’m from Brazil and I want to do this with my students. How did you make the connections at angles of 108 degrees? They are so perfect!
my chem teacher is so bad tysm
His voice is too soothing. It feels like I’m watching ASMR and am about to fall asleep.
Tha ks a lot sir u saved my day 😊😊love from India
comment section: “Leave a thumbs up is this man just saved your chemistry career just by doing this 20 min video.”
me: makes 20 more youtube accounts to like that comment so “guy” feels good about his content and his actual contribution to society
Sir thank u…u r the best explainer 🚶
You are a hero, sir. God fucking bless you.
In reference to your first example, BeCl2. I thought covalent bonds were between 2 nonmetals?
Nevermind, looks that it was explained further in your comments by someone already. lol
I realize that hydrogen seems to always go on the outside, but how come? Is it just the exception? Because isn’t Oxygen more electronegative than Hydrogen? I know Hydrogen is in Column 1A, so I always figured it was less electronegative. Just wondering, it’s got me a bit confused.
Thanks
than you saaw much
can you please make a video on titration and buffer solution
his videos are the only chem videos i can watch that actually make sense. i love them.
Is this the same as basic Lewis structure????
Isnt bent 105°??
Tyler saving asses since eternity.
THANK YOU! IF ONLY MY TEACHER TAUGHT THIS WAY THE FIRST TIME AROUND… AGAIN, THANK YOUUUU!
thank you so much….. It was so difficult for me till i saw this vidieo <3
He seriously explains this concept so well! Bravo!
i don tlike my chem teacher
Nice pedagogy job
This is so good
this video is so good wowzers
Don’t you mean LIKE charges repel?
thank yoooou sooooo much ❤️
He looks like logan paul
holy heck my teacher is awful
Martin sun why dont you pay him the it’s just a matter of 5 million dollars
Most satisfying video ever on vsepr….!!!!….#thxx #awsm😘😘
The Lewis dot structure isn’t correct , but great video!!
I AM JUST AWESTRUCK WITH YOUR EXPLANATION!!! THANK YOU SO MUCH!!!!
Hii sir firstly thank you for your videos and my small request is will you please do some videos about organic chemistry .Thank you sir.
Excellent
Please do not use the colors red and green . It is the most common Color blindness colors . Many color blind people will not be able to like it that much .
Thanks for this great video! 😀 It helped bunches!
You make me want to study Chemistry 🙂
You’re better than my teacher, thanks buddy
THank you
marry me 🙂
could you swallow any harder
Wait wouldn’t it just be Beryllium chloride not Beryllium dichloride since Be isn’t also a non-metal? Just asking because that is what I learned.
for NH3 it is just pyramidal ! thank you sir !
Thank you so much !
Umm, You are a better teacher than my own teacher.
God bless you
Tyler, you are so wonderful. Thanks for the helpful video.
Tylor, God bless you. You are such a wonderful teacher. So much love & respects.
you can change the first example to complete the valence shell of the beryllium atom just saying
That was Awesome
Very well representated .best video on vsepr theory ..got all my concepts clear
Dude I couldn’t pass my chemistry class without you ..
Thanks I appreciate all your videos my professor isn’t that fun watching as you again Thanks so much
And BTW why don’t they make video Books I’ll watch your videos all the time
Please make your videos with HD quality
Nature & Humanity it is
Nice
But wont those two lone Electron pairs of H2O repulse each other to get away ? Bcz in 3D u have showen the 2 pairs are very much close to each other.
Brilliant Stuff… Salute !
This guy is a very good teacher
the best teacher ever
Best explanation!
Please do a video on VBT and MOT!
Thank you sir.. Your video literally cleared all my doubts and misconceptions.
really love your videos…very interesting
Soo hard
How can I know if there is one bond or two or three in liner bond in BeCl, Co2,HCl
Best tr in World
You’re truly a gifted teacher! Thank you so much for all your videos.
keşke turkcesi olsaydı süper anlatmissiniz
In CH2O THE BOND angle is of 180 degree?
You are awesome thanyou man 😇
U are a god
You are a fantastic teacher. Thank-you so much for your videos. You make chemistry understandable!
Thank you, I am actually having an exam today and yo have just made this so clear. POWERFUL
!!
This video saved my life tbh, my chem professor doesn’t know how to teach very well and my textbook doesn’t do a very good job of explaining VSEPR groups. Seeing all the examples in 3D like this helped so much!
Thank God. YOU DESERVE more than those in Khan and Crash Crush. Thank you so so much!!
I can’t focus on the explanation. you are so damn good lookinggggg
Thank you for saving me throughout my premed in all my Chemistry Classes, you made Chemistry/easy to understand that I literally got a minor in biochem,THANK YOU SOOOOOO MUCH!!!!!!! My most favorite Youtube Professor, YOU ARE AMAZING!!!!! THANK YOOUUU SOOO MUCH!!!
Hi Tyler!
I am a full time Chemistry tutor in Singapore and was teaching VSEPR to my students when I came across your videos. and they are FANTASTIC! I am sharing my Chemistry knowledge on my Channel as well and I am glad to find an established YouTube educator who believes that showing your face in your videos DO make a difference in catching the student’s attention. I’ve featured your Channel on mine so hopefully you are cool with that. I’m really inspired by your success on YouTube. Hopefully I can do well too. Cheers!
Best regards,
Maverick
This guy is saving my chem grade. God bless
Your videos are really very helpful. thankyou sir. May God bless you.
but boron have 3 valence electrons
why did we cover this topic for a straight week in my class and i didnt get it, yet i watch this video not even halfway through and I feel like I completely understand VSEPR
**Mr. Tyler, I have a question regarding to the last example you gave, the bent shaped one with two pairs of electrons. I wanna know why the shape can’t be linear. Keeping t in mind, that if one pair of electrons stay at the top of the oxygen and the other at the bottom, both would repel equally and hence resulting to a linear shape. Why must the two pair of electrons stay at top and not repel each other?
other than that, your videos are the best! Topics I get taught in days in college, you teach me that in a few minutes!
i LIKED, SUBSCRIBED AND PUSHED the bell. this video helped me so much and I’m going to see the other videos thank you this video helped me. GREAT JOB
You Sir, are a gentleman and a scholar. My GPA and sanity thank you…as do thousands of others students I’m sure.
Why do i get sad when these videos end
thx God that i meant you, i’ve a test for tomorrow and i’ve prepare anything xD
Thanks! Helped a lot!
God bless ya for savin our lives..😂..2 long hours of lecture couldn’t get a single letter of VSEPR into my mind….DeWitt is LOVE….thanks tons buddy….continue savin lives !!!!
Supposedly god gave himself, which was the “son” to “save” us from hell, not to help you pass your chem exam.
TYLER!💪💪
It makes sense now
My school never explained the effect of lone pairs and I was so confused im so mad
This video helped a ton thank you
You have no idea how many times I said “OHHHHHHHHH”
it’s safe to say he taught over 1 million student in his life time
Man this guy deserves an award! I really appreciate your detailed videos, thanks.
I’ll give you my car and my bank account if you fly to the uk and take my chemistry exams for me
Unless you work for aqa then I’m only joking…
Thank you chemistry god.
You saved my life dude!
Thank you for making these videos. You are much appreciated!
opposite charges repels 🤔
Omg dude, thank you so much for this video. This has helped me grasp concepts and it has also made chemistry a lot more intriguing. Thank you once again.
Thanks alot I’ve learned sooo much from u,am gonna share this vedio with my friends 2 👌🏻😊
I actually come to the comment section to confirm if this video is good or waste of time until i saw someone saying ” this guy deserves 5 million dollars for his video”
Fucking Legend
Me:skipping to quickly see those structures with the angles,cuz it exam tmrw(12AM),rite now!!
What were those? At 2:15
Your lectures are really, really, really good for not only students who need a foundation in chemistry, but also college students who need to organize. I really recommend them.
Thank you!
Really your teaching methods are brilliant . Thanks a lot
Please make vedios on hybridisation also
literally you teach chem so easy
thank you!
Sir u r great
Sir you made a mistake on 7:47 to 7:51.
The most amazing chemistry teacher ever.
Even though chemistry is not my cup of tea, I can still listen and learn from you all day long and not get tired. You take things slowly and comfortably. 🙂
i feel happy that god has made such mens who understand the problems faced by us and resolve ot completely
AMAZING
awsome explanation. liked it very much
I have became your fan
Thank you
why does water has 104.5 degree btw the bonds but SO2 has 119 degree although both have a bent structure ?
Really nice…
God bless you sir, it has been great help.
You deserve atleast 5 Milllion Subscribers
This is incredibly helpful. Love your videos. Thank you!
Very good but I need the model of molecules of Methane
Thank you so much for making this video! I couldn’t understand the pictures on my book, but this video and your explanation makes it easier for me to get the concept. You’re a real educator…
1:38 You mean same charges repel
7:47 You mean 120° not 180°
Good video though 😉
Awesome. Thank you sir.
Olelelelele
That 3d models made me understand this concept really good.
10:50 Does the unpaired electrons push harder because it’s closer to the central atom?
How can we make those models?
This was very informative and nicely explained
7:48 nope it’s 120•
Anyways I’m so happy with your explanation
nice
Life saver!!
It was perfect! You helped me a lot! Thanks!!!
Suddenly I am more interested in Chemistry. Clear, well-explained concepts with such an amazing atmosphere. Loved every single minute. Though I barely spend 20 minutes on videos relating to Chemistry, this video has definitely changed my view on Chemistry. 11/10 would recommend. Thanks a lot for this video.
awsomeee
Please tell me you have videos for Organic Chem too
hello.. I want to ask if you can upload a video about Hybridization please.. your videos are helpful and you have a good way to explain the material..thanks for your effort
See the left hand at 0:11
It’s sad that some gamers or viners are much more recognised than you. You are a legend Mann. Thank you so much. A hero. 👏🏻
this is best method of teaching
I wish our teachers could teach us so well, with all these geometrical objects, but they just hand over the notes and it pretty much sucks.
We now know why teaching in India sucks
do you have a video the Lewis structure, or electron dot formula??
may god bless you with whatever you want in life man. LIfE sAvEr
Main lesson learned today: Electrons are really anti-social.
