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
- AA is false but R is true
- BA is true but R is false
- CBoth A and R are true and R is the correct explanation of A
- 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 .
