D)3
E)4

Question

Quizplus · Accepted Answer

The planar double-bond system in 3-methylcyclopentene involves two carbons, which are part of the double bond. The methyl group and the cyclopentene ring are not part of the double bond system, so they do not contribute to the carbons in the planar double-bond system. Therefore, the correct answer is C) 2.
