$A$ more powerful nucleophile favours $S_{N}1$ mechanism.

Vedclass · Answer

(A) The $S_{N}1$ reaction is a unimolecular nucleophilic substitution reaction where the rate-determining step is the formation of a carbocation intermediate.Since the nucleophile attacks only after the formation of the carbocation,the rate of the $S_{N}1$ reaction is independent of the concentration and strength of the nucleophile.$A$ more powerful nucleophile actually favours the $S_{N}2$ mechanism,where the nucleophile attacks the substrate simultaneously with the leaving group departure.Therefore,the statement that a more powerful nucleophile favours $S_{N}1$ is incorrect.

Which among the following is $NOT$ a correct statement about $S_{N}1$ reaction?
