Hello, I'm not sure if it's just my computer, but sometimes when I download the lectures, certain slides are missing. In this lecture specifically, the IR Spectrum of alkenes is missing. Any input? Thanks.

Are there print-outs for your all of your lectures? It would be so much easier to follow along if I had the spectrums in front of me. Thank you.

FYI - in the IR section (part 1), the lecture slide labeled 1-pentene, pulls up the pentane spectrum

In example 7, would you also include the C single bonded to the O of the OH group at 1250-1350?

During the IR example of 2-butanone, did you mislabel a ketone and carbonyl? I was under the understanding that a ketone was simply a C double bonded to an O, and that a carbonyl was when another C bond was present. I sounded like you explained that backwards though.

(that is, if it fits into both of those areas)

hello professor Starkey, your by far one of the best techers ive seen that teaches a chemistry lecture hands down. You are getting me through organic 1 an organic 2,so i just wanted to thankyou for that. My question to is, im a pre med bio/chemistry major an i have to take analytical chemistry as well as physical chemistry soon an i need lectures that cover those topics, so i wanted to know do you or do you know where i can find lectures like your's are but in the topics i need? thanks in advance...
