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

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 RCl to form RI . Further because I −   ion is a better leaving group than Cl − ion, therefore , RI is more rapidly hydrolysed than RCl to form ROH .
