Question

Which of the following statements regarding Friedel-Crafts reactions is wrong?

• A. Alkylation of benzene with an alkyl chloride requires only a catalytic amount of a Lewis acid such as aluminum chloride.
• B. Alkylation of benzene with an alcohol requires only a catalytic amount of a Bronsted acid such as phosphoric acid.
• C. Acetylation of benzene with acetyl chloride requires only a catalytic amount of a Lewis acid.
• D. Acetylation of benzene with acetic anhydride requires more than one equivalent of a Lewis acid.

Answer 1

The correct option is C Acetylation of benzene with acetyl chloride requires only a catalytic amount of a Lewis acid.

Acetylation of benzene with acetyl chloride requires only a catalytic amount of a Lewis acid.

it is wrong because of acetylation of benzene with chloride requires more amount of catalytic lewis acid
