Q. The increasing order of the rate of $HCN$ addition to compounds $A - D$ is $HCHO$ $CH_{3}COCH_{3}$ $PhCOCH_{3}$ PhCOPh
A) A < B < C < D
B) D < B < C < A
C) D < C < B < A
D) C < D < B < A
Explanation
(c)
Addition of HCN is nucleophilic addition. Greater the electron deficiency of carbonyl group higher the rate of reaction.
Hence,
