Which of the following reaction sequences will result in the formation of toluene from benzene? — Aromatic Hydrocarbons Chemistry Question

💡 Solution & Explanation

A is direct Friedel-Crafts alkylation yielding toluene. B is Gattermann-Koch reaction yielding benzaldehyde, which is then reduced by Clemmensen reduction to toluene. C is halogenation to chlorobenzene, followed by Wurtz-Fittig coupling with methyl chloride to yield toluene. D yields acetophenone, which reduces to ethylbenzene, not toluene.
