    These videos are great very comprehensible and I love being able to learn this important material for free!

    These videos really help me when I don't know understand what I learn in class

    do we have to worry about formal charges when dealing with resonance structure (like in your previous video)

    These videos makes me to understand more clear compare to when I am taught in class. thanks

    If you have question,use their website,link is in the description,there you'll see a list of there videos, click on the one you want, if it's not already highlighted ,then scroll down to the bottom of the page,it might sometimes take a bit to show up.there they have a conversation section, where there is a whole lot of answers to questions related to that specific video.
    There you could also signin and ask a question for your selves. It's great really.khan academy don't answer questions on TH-cam's comment sections,I think they use this platform to send videos for the revenue they might get from the views, after all it's very convenient, and they are a nonprofit organization,and it will help out.

    The valency of oxygen is two it requires one more bond for stability and the valency of nitrogen is 3 then how can it form 4 bonds . I request you to explain this sir.

    • @abelkahsai9599

      No, you misunderstand,the valency electron of nitrogen is 5 electron(3 electrons is what it need to reach a total of 8 electrons, meaning to reach octet), I think you confused valency number with valency electrons. The 3 electrons that it needs to reach 8 electrons is its valency number, valency number = 3. The same goes for oxygen has 6 valency electrons it needs 2 electrons(valency number)

    Does the hybrid structure have a negative charge?

  • @bushratasneem8891

    But shouldn't nitrogen have a lone pair??? Its octane should already be filled as it has a lone pair and 3 bond pairs.

    • @pokemonOBSESSER

      Bushra Tasneem nitrogen should only have a lone pair if there were leftover electrons, but since 18-18=0, there isn't. You need to fill all the terminal atoms (oxygens) first, and if the central atom (Nitrogen) does not have an octet than you make bonds.

    There is one other way of drawing the dot structure of NO2 and the dot structure I drew only had one formal charge and that charge belongs to the oxygen.
    What confused me is : your way of drawing the Dot structure (NO2) even it has three formal charges to deal, now what u said in the previous video where we were drawing the structure of (H2SO4) but their you explicitly said our goal should be to minimize the formal charge....
    What the heck are you doing with NO3😤😤😤😤😤

      you can put the speed on 0.75 if you find it hard to follow
      I'm watching on 1.5
      his pace is good
