Quizplus · Accepted Answer

- The IR peaks at 1603 and 1495 cm-1 suggest the presence of a conjugated carbonyl group (C=O) and an aromatic ring, respectively. - The ¹³C NMR having 7 signals indicates the presence of 7 unique carbon atoms. - The compound having one acidic proton suggests the presence of a carboxylic acid functional group (-COOH). - Only structure III satisfies all of the given criteria. It has a conjugated carbonyl group (peak at 1603 cm-1), an aromatic ring (peak at 1495 cm-1), 7 unique carbon atoms (7 signals in the ¹³C NMR), and a carboxylic acid functional group (one acidic proton).
