Quizplus · Accepted Answer

The parent structure is pentanone, a ketone with five carbons. We have a methyl group attached to the fourth carbon and another methyl group attached to the second carbon. Therefore, the correct name is 4-methyl-2-pentanone. Option A, 2-methyl-2-pentanone, is incorrect because both methyl groups are not on the same carbon. Option B, 2-methyl-4-pentanone, is incorrect because the first methyl group is not located on the fourth carbon. Option D, 2-methyl-4-pentanol, is incorrect because it has an -OH group, while the given compound is a ketone with a -C=O group.
