Question

Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R
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

• A. A is false but $R$ is true
• B. A is true but $R$ is false
• C. Both $A$ and $R$ are true but $R$ is $N O T$ the correct explanation of $A$
• D. Both $A$ and $R$ are true and $R$ is the correct explanation of $A$

Answer 1

Answer: (D)

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

Answer 2

The rate of hydrolysis of alkyl chloride improves because of better Nucleophilicity of I−
