Question

Quizplus · Accepted Answer

Compounds A, B, and D all have alpha hydrogens that can be removed by a strong base, forming an enolate ion. Compound C does not have an alpha hydrogen, so it cannot form an enolate ion. Therefore, choices A, B, and D would form an enolate ion on treatment with a base, but choice C would not. Thus, the correct answer is E, as all of the choices except C would form an enolate ion on treatment with a base.
