Statement-I: Nucleophilic substitution r...

Statement-I: Nucleophilic substitution reaction on an optically active alkyl halide gives a mixture of enantiomers.
Statement-II: The reaction occurs by `S_(N^(1))` mechanism.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion .

B

If both assertion and reason are true but reason is not the correct explanation of the assertion .

C

If assertion is true but reason is false

D

If assertion is false but reason is true .

Text Solution

Verified by Experts

The correct Answer is:
A
In `S_(N)1` mechanism racemization takes place which is due to inverting nucleopilic displacement of halongen atom from the alkyl halide by the halide in solution .
