Question
Assertion (A): Chlorobenzene is resistant to electrophilic substitution reaction.
Reason (R): C-Cl bond in chlorobenzene acquires partial double bond characters due to resonance.
Options
Both (A) and (R) are true and (R) is the correct explanation of (A).
Both (A) and (R) are true, but (R) is not the correct explanation of (A).
(A) is true, but (R) is false.
(A) is false, but (R) is true.
Solution
(A) is false, but (R) is true.
Explanation:
Because of resonance, chlorobenzene acquires a partial double bond, making it extremely reactive to electrophilic substitution processes.
