  • Chemguy, you are great!!! But I have 2 questions: how do you draw NO and NO2? And why is your name bannanaiscool?

  • this is an awesome video thanks but i have one problem with the cyanide compound...when it has 6 on the carbon and 2 on the nitrogen why does it become a triple bond why dont the 2 electrons go from the carbon to the nitrogen and make it a double bond?

  • @shrike993 Actually, it's a bit of a rule breaker. The N gets a formal charge of 0, and that's good, but the C gets a -1, and that's odd.

  • I´m a german person. And guess what. There arn´t any films about science by german teachers at you tube. My english isn`t so well, but anyway, I got it. This teacher is really great and maybe my English will work better , too.

  • Your English is far better than my German, and I AM a German!...Well, my dad was from Munich, anyway. Lederer is a German name...

    I'm glad you got it! Hope I can be of help,
