Vedclass · Answer

(C) The Assertion is true because $S_{N}2$ reactions involve the attack of a nucleophile from the side opposite to the leaving group,leading to the Walden inversion (inversion of configuration).However,the Reason is false. Aryl halides are extremely unreactive towards nucleophilic substitution reactions under ordinary conditions due to the partial double bond character of the $C-X$ bond caused by resonance. Therefore,they do not undergo $S_{N}2$ reactions with $KOH$ to form alcohols.

Assertion : $S_{N}2$ reactions always proceed with inversion of configuration.
Reason : $S_{N}2$ reaction of an optically active aryl halide with an aqueous solution of $KOH$ always gives an alcohol with opposite sign of rotation.
