Assertion (A):

SN^2

mechanism is accompanied by racemisation.

Reason (R): In

{S}{{N}}^2

mechanism, nucleophile attaches itself on opposite side, where halogen atom is present.

View answer and explanation

Correct option: D

A is incorrect; R is correct

Option D is correct because SN2 mechanism results in inversion of configuration, not racemization. The nucleophile attacks from the opposite side of the leaving group.
