Question

Quizplus · Accepted Answer

The compound is a cyclopentenone with a carbonyl group (C=O) on the second carbon atom. It also has two methyl groups on the 2 and 4 carbon atoms. Thus, the correct IUPAC name is 2,4-dimethylcyclopent-2-enone, which is option C. Option A is incorrect because it does not mention the cyclopentenone ring. Option B is incorrect because it mentions a cyclopenten ring instead of a cyclopentenone. Option D is incorrect because it has the carbonyl group on the wrong carbon atom. Option E is incorrect because the numbering should start from the carbonyl carbon.
