Assertion: `S_N2` reaction proceeds with racemisation while `SN_1` reaction proceeds with complete stereochemical inversion.
Reason : `S_N2` is two step reaction while `S_N1` is one step reaction.

A

If both (A) and (R) are correct and (R) is the correct explanation of (A).

B

If both (A) and (R) are correct, but (R) is not the correct explanation of (A).

C

If (A) is correct, but (R) is incorrect.

D

If both (A) and (R) are incorrect.

Text Solution

Verified by Experts

The correct Answer is:
D
`S_N2` reaction proceeds with complete stereochemical inversion, while `S_N1` reaction proceeds with racemisation. `S_N2` reaction is one step in which in coming nucleophile attacks from the side opposite to that of outgomgleavmg group and hence mv `S_N1` is at two step reactio in which carbocation is formed as intermediate and nucleophile can attack from either side resulting in racemisation.
