Reactions of Haloarenes - Electrophilic Substitution Reactions

Explain why the electrophilic substitution reactions in haloarenes occur slowly and require more drastic conditions as compared to those in benzene.

Assertion (A): Chlorobenzene is resistant to electrophilic substitution reaction.

Reason (R): C-Cl bond in chlorobenzene acquires partial double bond characters due to resonance.

How the following conversion can be carried out?

Benzene to 4-bromonitrobenzene

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.

Assertion (A): Alkylbenzene is not prepared by Friedel-Crafts alkylation of benzene. Reason (R): Alkyl halides are less reactive than acyl halides. In the light of above statements, choose the most appropriate answer from the options given below
