How the following conversion can be carried out?
Benzene to 4-bromonitrobenzene
Assertion: Aryl iodides can be prepared by reaction of arenes with iodine in the presence of an oxidising agent.
Reason: Oxidising agent oxidises I2 into HI.
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.
Assertion (A): Chlorobenzene is resistant to electrophilic substitution reaction.
Reason (R): C-Cl bond in chlorobenzene acquires partial double bond characters due to resonance.
Explain why the electrophilic substitution reactions in haloarenes occur slowly and require more drastic conditions as compared to those in benzene.
