@@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!
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 .
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
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❤❤❤
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 ❤
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....☺️.....
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.
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.
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
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
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.
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
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
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
First of all the graphics are EXCELLENT to the point where even a ninth grade chemistry student could understand VSEPR. However, I have a question, isn't ammonia's bond angle 107.3?
Thanks for the kind words! Ammonia actually has bond angles of 106.7. The lone pair has stronger repulsion leading to this bond angle. But the simulation in the video uses rather generic atoms so the angles aren't so precise. --- 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.
@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?
great video! i just wish it was a bit longer! Did you make any more videos on this? Not for specific molecules but general rules and practice problems?
@@wbreslyn Or maybe just make a playlist of all your VSEPR videos. I think that would work out great for people to rehearse and learn more. I'd watch it! Edit: Ok maybe i wouldn't watch all of it. You've made so many of these videos. But I'd watch some of it, or if you made a playlist with some selected videos of molecules of different shapes, probably all of it. Just not eight seesaw, fifteen bent, twelve trigonal planar etc etc.
@@5kunk157h35h17 Perhaps I could make a playlist of my best videos for each type of molecular geometry (bent, tetrahedral, etc). That might work. How do you think I could best let people know about such a playlist?
@@wbreslyn I'm not sure! I never uploaded videos to youtube. But maybe you could add some window links in this video? "More molecules with this steric number in this playlist", in one of those pop up windows in the corner. Or towards the end, a link to a playlist with different shapes. I'm not sure if you can link playlists like this though. If so maybe you could make a short video to describe the playlist/s and direct people from there. But i think that just by making a playlist people will stumble upon one of the videos and find the others more easily than now.
Unbelievable! The first professor who explains chemistry in a human language!
I try my 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.
I am soooooo thankful to find this channel, i understand so much better. thank you so much doctor wayne breslyn you are the best!

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.
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.

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.
