The only question I have is how can you tell which compound it is?

If we have internal and symmetrical alkyne, can we differentiate from normal alkane? Because what we can get from IR spectrum is only SP3 CH no SP CH and CC triple bond.

Honestly, you are a LIFE SAVER. My O-chem prof is good but goes off on tangents. You get right to the point. Succinct. Good explanations. I really hope I pass Ochem and if I do, it'll be because of you, Professor Starkey!

Hi Dr. Starkey, awesome lectures! They are life savers!. I have a question, does it depend on the finger print region if you wanted to deduce how long the compounds is. How for example can one tell if it's a butane or a decane, or like pentanol, hexanol, or octanol. They are all sp3 CH's with an alcohol at the end. Or a benzene with a longer substituent compared to a shorter one. Thank you.
