In the reaction `CH_(3)CHO+HCNtoCH_(3)CH(OH)CN` a chiral centre is produced. This product would be

A

Laevorotatory

B

Meso compound

C

Dextrorotatory

D

Racemic mixture

Text Solution

Verified by Experts

The correct Answer is:
D
`CH_(3)CHO+HCN rarr CH_(3)-underset(OH)underset(|)overset(**)(CH)-CN`
(Both d and l forms are obtained) Hence, product will be a racemic mixture.
