In an S N 1 reaction on chiral centres, there is:

In an SN1 reaction on chiral centres, there is:
  1. 100% racemization
  2. Inversion more than retention leading to partial racemization
  3. 100% retention
  4. 100% inversion

Solution

SN1 reaction gives racemic mixture with slight predominance of that isomer which corresponds to inversion because SN1 also depends upon the degree of 'shielding' of the front side of the reacting carbon.
