B) 1-phenyl-1-propanone

Quizplus · Accepted Answer

The compound has a phenyl group attached to a ketone functional group. The longest carbon chain is three carbons long, with the ketone group on the second carbon. Therefore, the correct IUPAC name is 1-phenyl-1-propanone. Choice A is incorrect because the benzophenone functional group has two phenyl groups attached to it. Choice C is incorrect because it implies a ketone functional group attached to a phenyl group that is attached to a propyl group, rather than the correct structure of a phenyl group attached to a ketone group, which is attached to a propyl group. Choice D is incorrect because it implies a ketone functional group attached to a propyl group that is attached to a phenyl group, rather than the correct structure of a phenyl group attached to a ketone group, which is attached to a propyl group.
