An SN^2 reaction of an asymmetric carbon...

An `SN^2` reaction of an asymmetric carbon of a compound always gives :

A

an enantiomer of the substance

B

a product with opposite optical rotation

C

a mixture of diastereomers

D

a single stereoisomers

Text Solution

Verified by Experts

In `S_(N)2` reaction, inversion of configuration occurs. Since the reactant and the product are not enantiomers, the sign of optical rotation may or may not change hence single stereoisomer is obtained.
