Q. In an $S_N1$ reaction on chiral centres, there is :
A) 100% retention
B) 100% inversion
C) 100% racemization
D) inversion more than retention leading to partial recemization
Explanation
[Solution] $S_N1$ gives a racemic mixture with slight excess of the inverted product, because the leaving group partly shields the front side of the carbocation. Answer (4).
