प्रश्न
Assertion (A): Chlorobenzene is resistant to electrophilic substitution reaction.
Reason (R): C-Cl bond in chlorobenzene acquires partial double bond characters due to resonance.
पर्याय
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.

Toluene reacts with a halogen in the presence of iron (III) chloride giving ortho and para halo compounds. The reaction is ______.
Assertion: In monohaloarenes, further electrophilic substitution occurs at ortho and para positions.
Reason: Halogen atom is a ring deactivator.
Give reason for the following:
During the electrophilic substitution reaction of haloarenes, para-substituted derivative is the major product.
Explain why the electrophilic substitution reactions in haloarenes occur slowly and require more drastic conditions as compared to those in benzene.
