Question

Assertion: The process of halogenation of benzene takes place in the presence of anhydrous FeCl₃.

Reason: Anhydrous FeCl₃ prepares nucleophile to attack the benzene ring.

Options

• Both Assertion and Reason are true and Reason is the correct explanation for Assertion.

• Both Assertion and Reason are true but Reason is not the correct explanation for Assertion.

• Assertion is true and Reason is false.

• Both Assertion and Reason are false.

Answer 1

Assertion is true and Reason is false.

Explanation:

Halogenation of benzene transpires in the presence of anhydrous FeCl₃, functioning as a Lewis acid catalyst. It facilitates the generation of the electrophile (Cl⁺) necessary for the electrophilic substitution process. However, the rationale is erroneous since anhydrous FeCl₃ does not generate a nucleophile; instead, it promotes the creation of an electrophile that attacks the benzene ring.
