Question

Which reagents are required for one step conversion of chlorobenzene to toluene?

• A. NaNO\textsubscript{2} + HCl
• B. CH\textsubscript{3}Cl/Anhydrous AlCl\textsubscript{3}
• C. CH\textsubscript{3}Cl/Fe, Dark
• D. CH\textsubscript{3}Cl, Na, Dry ether

Hint:

Friedel-Crafts alkylation is a common method for introducing alkyl groups to aromatic compounds.

Answer 1

The Correct Option is C

Chlorobenzene is converted to toluene via a Friedel-Crafts alkylation. This reaction utilizes methyl chloride (CH\textsubscript{3}Cl) and iron (Fe) in the absence of light, appending a methyl group to the benzene ring to produce toluene.
