Question

An SN2 reaction at an asymmetric carbon of a compound always gives (A) a mixture of diastereomers (B) a single stereoisomer (C) an enantiomer of the substrate (D) a product with opposite optical rotation

Tardigrade Admin · Accepted Answer

In SN2 reactions, the nucleophile attaches itself from the direction opposite to that of the nucleophile already present in the second step, the previous nucleophile is removed and a single stereoisomer is obtained.

Q. An $S_{N} 2$ reaction at an asymmetric carbon of a compound always gives

a mixture of diastereomers

a single stereoisomer

an enantiomer of the substrate

a product with opposite optical rotation
