identify the following functional groups by their IR absorbances on the IR
C=O
C=C
Homework Answers
A strong absorption band within the region 1650 to 1760 cm-1 is a clear indication of carbonyl group. In the above spectra we can see a absorptio around 1660cm-1 that is the clear indication of carbonyl. Due to chemical environment of carbonyl group the range can fluctuate in between 25-30cm-1.
Aromatic C=C appears at 1400-1580 cm-1 whereas normal C=C apppear at 1620-1680 cm-1. In the above spectra there is a sharp adsorption at 1587 which indicates the presence of C=C.
