This is a IR spectrum, I am trying to figure out if I am doing this
right?Base on this graph I think I have alcohol for my unknown
substance.
Homework Answers
Based on the given IR Spectrum, the unknown substance is:
amide (-CONH2).
3295-3198 cm-1 ---> two peaks, NH2 stretching,
2817 cm-1 ---> sp3 -C-H stretching,
1680 cm-1 ---> C=O (amide) stretching.

I am in chemistry 1, and trying to determine an unknown volatile
liquid. I have the boiling point (give or take 3 degrees celsius)
which is 85.0 degrees celsius. I also have the molecular weight

Infra red spectrophotometry graph which I was told is basically the
finger print of a substance. Do you know what substance this
