AIPMT PRELIMS 2003 Chemistry Stereochemistry MCQ Question

Type: MCQ-conceptual-Medium-Class 11

In this reaction: CH3CHO+HCN→CH3CH(OH)CN\text{CH}_3\text{CHO} + \text{HCN} \rightarrow \text{CH}_3\text{CH(OH)CN} an asymmetric centre is generated. The acid obtained would be:

A

D⁻isomer

B

L⁻isomer

C

50% D + 50% L - isomer

D

20% D + 80% L - isomer

Correct Answer

Option C

Detailed Explanation

The reaction forms a racemic mixture due to the formation of a chiral center, resulting in equal amounts of D and L isomers.
