  • wait. for CH2O why not just triple bond the C and O on the left one? Then it would be happier.

  • Glad to see you're thinking! If you do that, then the oxygen would be really mad. Oxygen is in period 2, so it can't have more than 8 electrons (an expanded octet). As you've suggested, it would have 10 electrons. :(

    Remember, oxygen "wants" 2 bonds and 2 lone pairs = 8 electrons. (Side note: in some structures, you'll see oxygen with 3 bonds and 1 lone pair = 8 electrons and a 1+ formal charge. Example: H3O+, the hydronium ion.)

  • Thanks for a great video on Lewis structures! And for showing how you can teach at home with your little one! :-)

  • OH SHIT

  • Very helpful. thank you!

  • Where are the answers shown for H202, HCN, CHCL3,CH20? I did not see them at the beginning of the next video which is Lewis structure nitrate anion as was mentioned

  • wow!!! Honestly THE best explanations I've ever seen. I dropped chem because of this and I'm retaking it and I am sure your videos will help me through. Thank You soooo much. You're awesome, keep it up.

  • why does carbon WANT to be in the middle,as it is the least electronegetive ??

  • amazing video

    ur explaination made it easy

    awesome work

    carry on the good work

  • can u plez show us how to draw the lewis structure for SO2Cl2? thanks a lot for helping us!
