During the Friedel-Crafts acylation of benzene using acetyl chloride and anhydrous , which of the fo — Aromatic Hydrocarbons Chemistry Question

💡 Solution & Explanation

The acylium ion is resonance stabilized, preventing skeletal rearrangements (making C false). $AlCl_3$ acts as a Lewis acid and strongly coordinates with the basic carbonyl oxygen of the newly formed ketone product, consuming the catalyst and necessitating a stoichiometric amount. Aqueous workup is required at the end to hydrolyze this complex and yield the free ketone (making D false).
