Question

In the reaction CH₃CHO + HCN → CH₃CH(OH)CN, a chiral centre is produced. This product is

(a) dextrorotatory 

(b) racemic mixture

(c) meso compound 

(d) laevorotatory.

Answer 1

The correct option is (b).

Explanation:

As during the reaction, a chiral carbon is created and further since the CN^- ion can attack the planer aldehyde group both from the top and the bottom face of the aldehyde group with equal case, therefore, a 50-50 mixture of the two enantiomers, that is, a racemic mixture is obtained.
