I was about to cry and give up with Organic chemistry when my professor introduced it with a little less than 2 weeks from the final. THANK YOU SO MUCH FOR EXISTING! I just may be able to pass, now :)
the videos are great, and thank you very much. But, whats up with the voice volume? Its knida low, or maybe the problem is with my headphones. Thanx again ;).
I was viewing other Ochem videos until finally...there is was on the side bar.... "khanacademy"....I was in heaven. He's like a brand..Nike, Microsoft,...but much more reliable. My search is over
As a note (I assume it will be covered in a later video anyway): the "octane" from the gas station is actually 2,2,4-Trimethylpentan, an isomer of octane. It has the same number of carbon and hydrogen atoms as the real octane, also no double bonds or cycles. But instead of a linear chain it has branches.
@superdau Its actually a mixture of the two (after reading the wiki article :)). Thus, the 'octane rating' is abundance of n-octane compared to and 2,2,4-trimethylpentane.

Wow, I haven't seen chemistry in 4 years (and I'm also not so smart), but Sal's amazing teaching style made this so easy for me to understand.
