Question

In an SN1 reaction on chiral centres, there is

1. 100% racemisation
2. inversion more than retention leading to partial racemization
3. 100% retention
4. 100 inversion

Answer 1

Correct answer is option 2) inversion more than retention leading to partial racemization

In S_N1 reaction, there is slight more inversion product than retention product because S_N1 reaction depend on shielding effect of the front side of the reacting carbon.
