Stereoisomers can exist in the case of which of the following?
A)The hydrazone of benzophenone
B)The oxime of 2-methylcyclopentanone
C)The phenylhydrazone of 4-methylcyclohexanone
D)The imine of cyclopentanone
E)Two of these choices.

Question

Quizplus · Accepted Answer

Stereoisomers can exist in molecules that have chiral centers or can form geometric isomers due to restricted rotation around a bond. The oxime of 2-methylcyclopentanone (B) and the phenylhydrazone of 4-methylcyclohexanone (C) can both exhibit stereoisomerism. In the case of B, the oxime can have stereoisomers due to the presence of a chiral center in the cyclopentanone ring when substituted. For C, the phenylhydrazone of 4-methylcyclohexanone can have stereoisomers due to the chiral center in the cyclohexanone ring and the configuration around the newly formed double bond in the hydrazone.
