Question

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.

Answer 1

Correct Answer - 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.
