Quizplus · Accepted Answer

The aldol reaction of cyclopentanone involves the enolization of cyclopentanone followed by nucleophilic attack of the enolate ion on another cyclopentanone molecule. The resulting intermediate can undergo either intramolecular or intermolecular dehydration to form different products. In this case, the intramolecular dehydration is preferred and leads to the formation of a cyclic aldol product. The only cyclic aldol product among the options provided is III, where the enolate attacks the carbonyl group at the β-position and forms a five-membered ring. Therefore, the correct answer is C.
