Which of the following form a crystalline addition compound with saturated aqueous $NaHSO X_{3}$ ?

A $CH X_{3} CH X_{2} - CO - OC X_{2} H X_{5}$
Bcyclohexanone
C $CH X_{3} CH X_{2} - CHO$
D $C X_{6} H X_{5} - CO - C X_{6} H X_{5}$

Answer: B, C

Propanal (aldehyde) and cyclohexanone (unhindered cyclic ketone) add bisulphite. Benzophenone is a diaryl ketone and is hindered and conjugated, so it does not. The ester ethyl propanoate lacks an electrophilic carbonyl of this type.
