@@wbreslyn you have no idea how great you are I am so thankful you are a person please keep up the great work. Carrying me in chemistry starting from today.
In 11 minutes this video managed to teach me a concept that I've struggled with all semester. 14 weeks of Chemistry class, and never once has my professor uttered the phrase "steric number". The explanation of that once concept alone was literally the missing puzzle piece that helped me figure out why I was struggling with molecular geometry. And learning how to do that led to the realization of why I was struggling with Lewis structures on top of it. My professor "doesn't believe in reviews" so we go over things once in class, and that's it. Your videos are probably the only reason I'm confident that I won't fail my final exam this week. Thank you so much Dr. B!!
I have been struggling with chemical bonding in general. I can’t skip it since it’s in my syllabus for NEET and school as well. You, sir, are a saviour for people like me. I pray to god that you may live long and teach those of us who need videos like these. Thank you!
Yeah, I really find those help me understand the chemistry. This is the app I used: phet.colorado.edu/sims/html/molecule-shapes/latest/molecule-shapes_en.html --- Dr. B
This was amazing. You did a great job explaining this. My textbook and lectures were a bit overwhelming but actually being able to see how these atoms interact with each other truly makes me feel 10x better on this subject. It just makes me enjoy chemistry so much more. I am definitely going to spread this video as well as the simulator to my class cause this was truly immaculate work.
Thank you for the kind words! I agree the visualizations make a huge difference in how we think about the atomic interactions. Here's the app I used in the video: phet.colorado.edu/sims/html/molecule-shapes/latest/molecule-shapes_en.html .
Hey Dr. B, I just wanted to express my heartfelt gratitude for the insightful video you shared on the Vesper theory and its geometrical aspects. Your explanation was incredibly clear and thorough, making it much easier for me to grasp the concept. Thank you so much for taking the time to create such valuable content. I truly appreciate it!
Amazing work!!! This is the smoothest and most easy to understand explanation of molecular geometry ever!!! Thank you for making confusing chemistry topics easy to comprehend.
The BEST video on RUclips....Huge Thanks for making this concept easy to understand with those amazing graphics and explanations......Once again Thanks a lot....☺️.....
Thank you so much! Due to the pandemic my college is closed so I am kinda on my own when it comes to studying. Your videos have helped my alot with the exercises in "Chemical Principles" by Atkins.
That's a good way to do it, combine videos online with a textbook. Chemistry is difficult even in the best of times and the pandemic makes it tougher. All the best! --- Dr. B
I know I’m super late but dr.B you are the BESTTTT I got all 4/5 right structures in my test and I learnt it all in a few minutes thankyou so much you are a life saver❤❤❤
Dr. B is the first professor to put molecular geometry in layman terms I have struggling with for the past few hours now actually the statement which broke it all down was *we are concerned with only the amount of bonded atoms not the type of bonds whether double triple or single* I had been making silly mistakes over the types of bonds present and would end up getting a steric number as high as 7 🤧🤧 thank you Doc ❤
Man.. you got that it's all going to be alright voice, It's literally super scary to not understand something and look it up online and feel like there's even more things you don't understand, but with Dr. B, it just all makes sense and makes things feel okay. Thank you so much
Great video encompassing moleculaar geometry. was concise and simple, very hard to find stuff like this on RUclips. You saved me for my midterm in 4 hrs
This video was amazing! I had a general grasp of the concept from reading the textbook and my notes along with the lectures from my professor, but I was still unable to keep them straight. This video broke the shapes down in a such a manner and explained them thoroughly enough--but not too deeply--so that I was able to understand them.
Thankyou for sharing sir! I would like to make a humble suggestion, you should also put one slide of 1-2 seconds displaying the solutions to the practice questions so that we can pause and check ours. That way we won't have to look up the internet for verifying our answers- that being a time-consuming task and it would therefore, enhance our confidence.
Thanks, Carl. I used the PhET website for the graphics. It really gets the idea across of how the atoms repel each other to give the molecule i's geometry. Now I need to do the VSEPR for the higher steric numbers... --- Dr. B
I have a question about double bonds and BF3. 2:58 is where it starts. The lewis structure shows 2 electrons shared between the B and the 3 Fs, but the VSEPR only showed 1 connection. Should it have showed 2 bonds or do I not understand what a double bond is. Thanks for any clarification.
Thank You for this video this clarified a few things and was a good revision of the things I've already learned in my chemistry class for school I appreciated it.
Ive been trying to understand this topic our tutor skipped the explanations saying it would waste our time (he's still the best though) but this video is explicit
@5:00 why is the N in nitrite shown with 1 whole lone pair (2 electrons in total)? If N has 5 valence electrons and 1 O is taking 2 from a double bond, then the other O should take 2, leaving N with 1 single valence electron. Especially since it has a -1 charge as a polyatomic ion, therefor giving it "1 lone pair" makes it neutralized, thus not having a -1 charge. Right? I find lewis structures on various websites showing both your and this other lewis structure for nitrite. But my confusion is with the way many other lewis diagrams are shown. Which one is correct, and why?
Thanks, glad I could help and all the best on your journey. I'm still on my own chemistry journey and making these videos helps clarify and distill my thinking ... --- Dr. B
The lone pairs are determined by the Central atom, so it doesn't matter if their are lone pairs with the attached atom if their aren't any in the central atom than, it doesn't apply that their are lone pairs therefore the geomatrical shape changes
Hi! I have a test on this, lewis structure, and bonds tomorrow. Do you have any tips on how I can study in addition to watching videos? I'm confused on how to determine the shape, and electron dots.
Often they are omitted since they don't impact the shape of the molecule. This is often done for clarity and simplicity. Since F always obeys the octet rule we know that they are there. But I should have put them in to be consistent with the other molecules in the video!
You're right. We would expect it to be a bit less, how much less depending on what the two atoms were. I didn't emphasize that much in the video but all of these angles are rather general and there are variations. --- Dr. B
I was taught, that the bond angle for a tetrahedral with lone pairs of electrons, would be slightly lower than a standard tetrahedral. I was told that a tetrahedral with one lone pair would have a bond angle of 107.3, while a tetrahedral with two lone pairs would have a bond angle of 104.5. Is this not correct?
Yeah, the simulations on the PhET website helped me a lot with this video. phet.colorado.edu/sims/html/molecule-shapes/latest/molecule-shapes_en.html Glad I could help you with VSEPR! ---- Dr. B
Unbelievable! The first professor who explains chemistry in a human language!
I try my best!

I am soooooo thankful to find this channel, i understand so much better. thank you so much doctor wayne breslyn you are the best!
When he explained how the lone pairs "pushes it down", that is what really made it click for me. I was able to imagine how the shape would look.

For the very first time someone did it better than organic chemistry tutor for me! Amazing! Thank you sire!🙌🏽
Sweet, that has been one of my personal goals for a long time!
You are the goat of chemistry youtubers. Thanks!
This channel deserves more subscribers
Who else is here because your were so bored in class & now you regret it?
Mee lol

Just amazing. Really explains molecular geometry thoroughly. Thanks a lot, Dr. B
Anytime!
This was so helpful. it helped me understand something I had no clue how to do. Thanks!
4:41 shouldn't the bond angle be 117.5⁰. lp-bp repulsion>bp-bp repulsion according to VSEPR
Thanks for explaining. This was straightforward to follow, and it helps alot. Thank you.
This is a great video I've ever met. Than you Professor for this perfect video. waiting for more videos to come. Blessing
You explained it better in 11 minutes than my teacher in 1 year of teaching this
Excellent explanation! with chart and visual clarity. You rock! David
This video made me understand that impossible topic....... Superb and thank you very much
You are most welcome!
Such a great explaining talent 🙂
Thank you! 😃

Anytime!
Thanks Dr B it helps so much. More please 🙏 ❤
Maybe the best chemistry lecture in the world
Thanks for the kind words! --- Dr. B
Excellent explanation easy to understand thanks for video
I have a question about double bonds and BF3. 2:58 is where it starts.
The lewis structure shows 2 electrons shared between the B and the 3 Fs, but the VSEPR only showed 1 connection.
Should it have showed 2 bonds or do I not understand what a double bond is.
Thanks for any clarification.
One bond consists of two electrons. Or we can say, each atom shares an electron(to get two electrons) with another, that forms a bond.
Wow, thats such a neat explanation. I'm glad I came across this video.
Glad it was helpful!
So cute 😊 thank you for clearing visualization confusion
You're welcome 😊

Ive been trying to understand this topic our tutor skipped the explanations saying it would waste our time (he's still the best though) but this video is explicit
5:03 How come in BF3 Lewis Structure, boron has only 6 dots surrounding it and not 8? Shouldn't one of the fluorines be double bonded?
Thank you !!!!!! You are helping for my university exam

Very nice and very clearly explain🎉🎉
great video, but in SO2, why S has ten valence electrons?
Superb!! Helped me so much thank you🎉🎉
You're welcome!
Wow that was really helpful explaination.Thank uu
3:45 HNO2 is the proper oh no! Just randomly rearrange the letters and you get OHNO. Tbh the structure is actually H-O-N=O.
always nice refresher, hope your doing well Dr. B
Hey Peter! So good to hear from you! All is well here, hope you are still running fast.

Glad it helped!
You’re hilarious. I love your oh-no! Molecule 😂😂😂
4:47 I just died lmao
Thank you so much the visuals really help I couldn’t visualize it in class. this will really help with my next test
Edit: I got and 85😁👍
You are most welcome and congrats on the 85!
Why are the unshared pairs for the fluorine atoms not shown on the trigonal planar model of BF3?
Often they are omitted since they don't impact the shape of the molecule. This is often done for clarity and simplicity. Since F always obeys the octet rule we know that they are there. But I should have put them in to be consistent with the other molecules in the video!
Profuse thanks for clarifying this topic!
No problem, glad I could help! --- Dr. B
감사합니다! Thank you! 🙏
Does the lone pair not have a stronger repulsion than other bond domains? So how would the angle be 120°? Shouldn't it be less?
You're right. We would expect it to be a bit less, how much less depending on what the two atoms were. I didn't emphasize that much in the video but all of these angles are rather general and there are variations. --- Dr. B
I was taught, that the bond angle for a tetrahedral with lone pairs of electrons, would be slightly lower than a standard tetrahedral.
I was told that a tetrahedral with one lone pair would have a bond angle of 107.3, while a tetrahedral with two lone pairs would have a bond angle of 104.5.
Is this not correct?
I think I got my answer in the ending of your video. :)
Amazing this explanation!
