B) N-ethylaniline

D) N-ethyltoluidine

Quizplus · Accepted Answer

The compound contains an ethyl group attached to the nitrogen of an aromatic ring, which is characteristic of aniline derivatives. The correct way to name this compound is to use the prefix "N-ethyl" to indicate the position of the ethyl group on the nitrogen of the ring. Option A, 1-ethylaminobenzene, is incorrect because it would imply that the nitrogen is part of an amine group rather than aniline. Option C, N-ethylcyclohexanamine, is incorrect because it would imply that the nitrogen is part of a cyclohexane ring rather than an aromatic ring. Option D, N-ethyltoluidine, is incorrect because it would imply that the nitrogen is part of a toluene derivative rather than aniline.
