Question

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.

Answer 1

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.
