Friedel-Crafts acylation is generally preferred over Friedel-Crafts alkylation for the synthesis of — Aromatic Hydrocarbons Chemistry Question

💡 Solution & Explanation

In alkylation, the introduced alkyl group activates the ring, causing uncontrollable polyalkylation. In acylation, the acyl group is powerfully deactivating, acting as a shield against further electrophilic attack and ensuring clean mono-substitution.
