Question

Quizplus · Accepted Answer

Oximes can exist as E/Z isomers, therefore, stereoisomers can exist for the oxime of 2-methylcyclopentanone. The hydrazone of benzophenone and the imine of cyclopentanone do not have chiral centers and cannot have stereoisomers. The phenylhydrazone of 4-methylcyclohexanone can exist as a mixture of syn/anti isomers, but not as stereoisomers. Therefore, the correct answer is B.
