So much better than learning from my professor's awful Powerpoints...

Its like he's stabbing the board!

@ksoccerz19 Try to watch again at 10:00. I think he mentioned about it. "you will never have more than 1 carbon 13 cause there has only got 1.1% abundance. But all of the bromine are either 79 or 81. These are both very likely.50% chance." hope that helps. Have fun!

Please go teach at my university! The chemistry department NEEDS someone like you!

Why is carbon assumed to be 12 in the calculation of CH2Br2? Didn't you say that carbon could be 12 or 13? i'm really confused... help?

omg he looks like the guy from two and a half men!

Man i did Msc in 2005 we had to study lot books make it clear. After five years I need to study it again for some reason, you are really helpful and made it so clear from basic. I wish I had a teacher like you during my studies.
