Question

Friedel-Crafts acylation reaction is proceed via ________.

• A. electrophilic substitution reaction
• B. nucleophilic substitution reaction
• C. both $A$ and $B$
• D. none of these

Answer 1

The correct option is A electrophilic substitution reaction

Friedel-Crafts acylation reaction is proceed via electrophilic substitution reaction. The lewis acid catalyst $AlC{l}_3$ combines with acid chloride to generate electrophile ($R-C^{+}=O$), which is then attacked by benzene ring and undergoes substitution reaction.

Hence, option $A$ is correct.
