Vedclass · Answer

(C) The $S_N2$ mechanism is a concerted,single-step process where the nucleophile attacks from the backside of the leaving group. It involves the simultaneous breaking of the $C-X$ bond and the formation of the $C-Nu$ bond through a pentacoordinate transition state. It does $NOT$ involve the formation of a carbocation intermediate,which is a characteristic feature of the $S_N1$ mechanism. Therefore,option $C$ is not a feature of the $S_N2$ mechanism.

Which among the following is $NOT$ a feature of $S_N2$ mechanism?
