Solution

Q.
Assertion A: Hydrolysis of an alkyl chloride is a slow reaction but in the presence of $NaI$ , the rate of the hydrolysis increases.

Reason R: $I^{-}$ is a good nucleophile as well as a good leaving group.

In the light of the above statements, choose the correct answer from the options given below: [2023]

1 A is false but R is true

2 A is true but R is false

3 Both A and R are true but R is NOT the correct explanation of A

4 Both A and R are true and R is the correct explanation of A

Ans.
(4)

$I^{-}$ being a good nucleophile forms $R - I$ which gets hydrolysed readily.
