A and B in the following reaction are
R - C - R' `overset("HCN/KCN")(rarr) overset(B)(rarr)`

A

B

C

D

`A=RR'CH(CN)_2 , B= NaOH`

Text Solution

Verified by Experts

The correct Answer is:
A
Addition of KCN/HCN is cyanohydrin addition product formation on the given ketone and hence compound A formed should be RR. C (CN) (OH). The second reaction involves reduction of the cyanide to a primary amine which can be done only by using Li`[AlH_(4)]`among the above choices.
