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

Options

  1. A100 % racemization
  2. BInversion more than retention leading to partial racemization
  3. C100 % retention
  4. D100 % inversion

Correct answer

B. Inversion more than retention leading to partial racemization

Step-by-step solution

S N 1 reaction gives racemic mixture with slight predominance of that isomer which corresponds to inversion because S N 1 also depends upon the degree of 'shielding' of the front side of the reacting carbon.
