Involve only backside attack of nucleophile.

Vedclass · Answer

(A) The $S_N1$ mechanism proceeds via the formation of a planar carbocation intermediate.Because the carbocation is planar,the nucleophile can attack from either the front side or the back side.This leads to both inversion and retention of configuration,resulting in a racemic mixture if the substrate is chiral.Backside attack is a characteristic feature of $S_N2$ mechanisms,not $S_N1$.Therefore,option $A$ is $NOT$ a feature of $S_N1$ mechanisms.

Which among the following is $NOT$ a feature of $S_N1$ mechanisms?
