Assertion A : Hydrolysis of an alkyl chloride is a slow reaction...

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

Reason R: I−{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.

Options

  1. AA is false but R is true
  2. BA is true but R is false
  3. CBoth A and R are true and R is the correct explanation of A
  4. DBoth A and R are true and R is not the correct explanation of A

Correct answer

C. Both A and R are true and R is the correct explanation of A

Step-by-step solution

Iodide ion is a powerful nucleophile and hence reacts rapidly with RClRCl to form RIRI. Further because I−{I}^{-}ion is a better leaving group than Cl−{Cl}^{-} ion, therefore , RIRI is more rapidly hydrolysed than RClRCl to form ROHROH.
