Question

an Sn1 reaction at the asymmetric carbon of an enantiomerically pure chiral alkyl halide gives an product
(a )with retention of configuration
(b )with inversion of configuration
(c )with recemisation
(d) with partial racemisation​

Answer 1

Answer:

(d) with partial racemisation because there will be inversion more than retention and it will be partial racemisation.

Answer 2

The correct option is d.

• In the Sn1 reaction, a tertiary alkyl halide reacts with a nucleophile in the presence of a polar protic solvent to give a product.
• In this reaction, the nucleophile can attack from both the front side and backside so, racemisation occurs.
• Again at the intermediate ion pair stage the nucleophile attack from the back side and give 2-20% inversion product.
