In an reaction on chiral centres, there is:

  1. A
    retention
  2. B
    inversion
  3. C
    racemization
  4. D
    Inversion more than retention leading to partial racemization

Solution & Step-by-step Explanation

In reactions, the intermediate carbocation is planar. The nucleophile can attack from either side, theoretically leading to racemization. However, in practice, the departing leaving group may partially shield one side of the carbocation, leading to more inversion than retention (partial racemization).
