Which of the following statement regarding `S_(N)1` reaction shown by alkyl halide is incorrect?

A

The added nucleophile plays no kinetic role in `S_(N^1)` reaction.

B

The `S_(N^1)` reaction involves the inversion of configuration of the optically active substrate.

C

The `S_(N^1)` reaction on the chiral starting material ends up with race mistration of the product.

D

The more stable the carbocation intermediate the faster the `S_(N^1)` reaction.

Text Solution

Verified by Experts

The correct Answer is:
B

In `S_(N^1)` reaction, rate of substitution depends on the concentration of substrate. In case of `S_(N^1)`reaction there si racemisation. `S_(N^1)` reaction will be faster, if carbocation formed is more stable.
