    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!!

    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.

  • @marigeo24
    @marigeo24 Рік тому

    @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?

    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
      @damarisdeng3571 4 роки тому

      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.
