Assertion: Aryl halides undergo nucleophilic substitution reactions with ease.
Reason:The carbon halogen bond in aryl halides has partial double bonds character.

A

Statement 1: is true Statement 2: is true, Statement 2 is the correct explainion of Statement 1

B

Statement 1 is true, Statement 2 is true, Statement 2 is not the correct explainion fo Statement 1.

C

Statement 1 is true, Statement 2 is false.

D

Statement 1 is false, Statement 2 is true.

Text Solution

Verified by Experts

Aryl halides do ot undergo nucleophillic substituion reaction under ordinary conditions. Thus, statement `1` is incorrect. In aryl halides, the carbon-halogen bond has a partical double bond character, so it becomes shorter and stronger and cannot be easily reaplaced by a nuclephile. Statement 2 is true.
