Quizplus · Accepted Answer

The compound given can be identified as a derivative of benzoic acid with a methyl group substitution on the aromatic ring at the 3 position. Therefore, the correct IUPAC name is 3-methylbenzoic acid. Option A is incorrect because it indicates the methyl group is attached to the carboxylic acid group, which is not the case. Option B is also incorrect because it implies the same attachment as option A. Option D is incorrect because it uses the suffix -ate, indicating a salt or an ester, whereas the given compound has a carboxylic acid functional group.
