Chemistry - Halogen Derivative Question with Solution | TestHub

${\text{S}}_{\text{N}}1$reaction occurs through the formation of carbocation as intermediate. Hence, rearrangement occurs in${\text{S}}_{\text{N}}1$reaction and not in${\text{S}}_{\text{N}}2$reaction.${\text{S}}_{\text{N}}1$reaction is favoured in presence of a polar protic solvent and a weak nucleophite. These reactions can be catalysed by the some Lewis is acid. A strong nucleophile is an aprotic solvent increases the rate of${\text{S}}_{\text{N}}2$reaction. Hence, option$\left(\text{B}\right)$in incorrect.
