@@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!
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❤❤❤
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 UA-cam....Huge Thanks for making this concept easy to understand with those amazing graphics and explanations......Once again Thanks a lot....☺️.....
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
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.
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 ❤
Great video encompassing moleculaar geometry. was concise and simple, very hard to find stuff like this on UA-cam. You saved me for my midterm in 4 hrs
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.
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.
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
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
@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?
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
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.
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
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
Ive heard this is the one of the hardest things to learn in ap chem but i think i might be a whiz even before class starts if i keep watching your videos
Unbelievable! The first professor who explains chemistry in a human language!
I try my best!

I watch this guy so much that he’s practically my chem teacher in school
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 best thank you so much! I am currently revising for my chemistry exam and your videos help so much
Great video encompassing moleculaar geometry. was concise and simple, very hard to find stuff like this on UA-cam. You saved me for my midterm in 4 hrs
Studying for the MCAT currently. This was super helpful! Thank you!
All the best on the MCATs!
I am soooooo thankful to find this channel, i understand so much better. thank you so much doctor wayne breslyn you are the best!
You are the goat of chemistry youtubers. Thanks!
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.
much more better and understandable than my lectures.
Glad I could help!
Literally amazing. Watched many videos but nothing beats this
Hey thanks! And I just did a video guide for this topic:
breslyn.org/guides/Bonding/Bonding-Molecular-Geometry.pdf
This channel deserves more subscribers
I cant stress how much this video helped me. Thank you
Glad it helped!
Just amazing. Really explains molecular geometry thoroughly. Thanks a lot, Dr. B
Anytime!
thanks a lot doctor B. with this I can finally understand what my teacher is discussing about
Who else is here because your were so bored in class & now you regret it?
Mee lol
me🤣🤣
Hahahahahahahahahaha me!
4:41 shouldn't the bond angle be 117.5⁰. lp-bp repulsion>bp-bp repulsion according to VSEPR
Prof.Breslyn, YOU ARE THE BEST! You explain everything so well🥇🥇🏆🏆🏆🏆🏆🙏🙏🙏🙏🙏
This was so helpful. it helped me understand something I had no clue how to do. Thanks!

You explained it better in 11 minutes than my teacher in 1 year of teaching this
This video made me understand that impossible topic....... Superb and thank you very much
You are most welcome!
This is a great video I've ever met. Than you Professor for this perfect video. waiting for more videos to come. Blessing
1 day before test… looks like I’ve known it for century❤
Thanks for explaining. This was straightforward to follow, and it helps alot. Thank you.

Thank you very Much you helped me so Much (i am from Tunisia and i am a university student) n'est Channel keep it UP)
Happy to help!
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.
Amazing! Thank you for the great explanations and visuals!
Best video on molecular geometry. Thank you so much!
I owe a lot to the visualization software at
phet.colorado.edu/sims/html/molecule-shapes/latest/molecule-shapes_en.html
--- Dr. B
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?
So cute 😊 thank you for clearing visualization confusion
You're welcome 😊
I was finding a video which could explain it like u did.... Thanks 👍
You are welcome 😊
Wow, thats such a neat explanation. I'm glad I came across this video.
Glad it was helpful!
Superb!! Helped me so much thank you🎉🎉
You're welcome!
Very nice and very clearly explain🎉🎉
Wow that was really helpful explaination.Thank uu
Great teaching style!
For Ohh Noo!!😮😮 Also called NO2- got me laughing 😂😂😂5:46
The explanations were amazing. Thank you so much🖤
You're so welcome!
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.
🏃♂️
you sound like kevin conroy lol... you're helping me so much i just discovered you today
Interesting, no one has said that before. Often I'll get Jerry Seinfeld.
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.
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
This was amazing👍
Thanks professor
Anytime!
Thank you so much! So grateful for this video. I actually get it now.
Glad it helped!
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!
This was amazing, very nicely explained. Thank you.
