Question

What functional groups are present in salicylic acid?

Answer 1

There are three distinct moieties that contain 2 functional groups.

Explanation:

Salicylic acid (2-hydroxybenzoic acid) is formed of a benzene ring to which 2 adjacent groups, carboxylic group and hydroxy group, are attached. We don't normally consider benzene to be a functional group, so that's why the hydroxyl and carboxylic are the ones that count.
