Question

Without exception, $S_{N^2}$ reaction at chiral carbon gives:

• A. enantiomer of substrate
• B. product of opposite polarity
• C. diastereomeric mixture
• D. only one stereoisomer

Answer 1

Answer: (A)

enantiomer of substrate

$S{N}^2$ reaction at chiral carbon give the product of opposite configuration.As immersion occur if reactant is R then product will be S.
