@@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!!

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 .

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.

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!

Visualizations paired with explanations like this have changed my understanding of chemistry forever. Thank you.

Your work is truly unappreciated. I really thank you for helping me and many other people. Thanks Professor!

Great video encompassing moleculaar geometry. was concise and simple, very hard to find stuff like this on KZread. 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.

This was so helpful. it helped me understand something I had no clue how to do. Thanks!

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.

@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 so much! you make the chemistry more interesting. :)

I was finding a video which could explain it like u did.... Thanks 👍

Very nice and very clearly explain🎉🎉

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

Wow, thats such a neat explanation. I'm glad I came across this video.

That is great explanation prof!! Btw what is the software you use to demonstrate all of this series? I want to try too... if it is available for free.

Sir why the lone pair bents the model?

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.

@damarisdeng3571

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.

Such a great explaining talent 🙂

Why are the unshared pairs for the fluorine atoms not shown on the trigonal planar model of BF3?

@wbreslyn

8 ай бұрын

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!

much more better and understandable than my lectures.

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?

@wbreslyn

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
