Vedclass · Answer

(A) The $S_N1$ reaction proceeds via the formation of a planar carbocation intermediate. Since the nucleophile can attack from either side of the planar carbocation,a racemic mixture is formed. However,because the leaving group partially blocks the front side (ion-pair effect),the attack from the back side is slightly favored. Therefore,there is inversion more than retention,leading to partial racemisation.
