This is from a lab to separate an unknown binary mixture. This compound after performing a solubility test, I determined to be a carboxylic acid. I need help in identifying the peaks and determining what they are.
Is hard to identify a compound only with IR
Don't see any carboxylic peak. The carboxylic peak are very large, usually over 3200. Not this case.
The 3054 signal is C-H sp2 stretching
The 2998 signal is C-H sp3 stretching
I ' m not sure if the low signals at 2850 and 2685 can be attributed to an aldehydic group (usually they have two weak signal at around 2800-2700) .
It could be....because we know we have a C=O group (1700 signal)
