Question

Identify the key IR absorbances in your spectra for BOTH the phenol and adipic acid that help to identify each of those structures.

Phenol:

Absorbance (cm-1)

Functional group

Adipic acid:

Absorbance 9cm-1)

Functional group

Explanation / Answer

The IR mentioned above is not due phenol and adipic acid

adipic acid will have carbonyl streaching frequency at around 1650 cm-1 and OH streaching at around 3300 cm-1

and CH2 streaching frequnency at 2950 cm-1

phenol will have OH streaching at around 3300 cm-1 and aromatic C=C streaching at around 1500 cm-1
