I've memorized the most important ones like aldehydes, ketones, alcohols, acids.

But what about nitriles, alkenes, alkynes, ethers? (these are mentioned in Destroyer)

 

[GSUeagle2011]

Nitriles and terminal Alkynes (internal Alkynes are IR inactive) both have a peak around 2200 and the C-H (sp) on the terminal alkyne gives a signal around 3200. Alkenes give a signal around 1650 and aromatic cmpds give signals ranging from 1500-1600. Alkane sp3 C-H bonds give a signal to the right of 3000 and alkene or aromatic sp2 C-H bonds give a signal just to the left of 3000.

Since the exam randomly picks questions from a question bank, I think you got an easy version of the exam across the board. Lucky bastard! lol.

What did you use as a good luck charm?

He didnt get IR question doesnt mean his exam is easy 🙂

I got one (or 2) IR questions but they are easy. Remember IR questions that appear in Destroyer.
