Question

What happens when benzene reacts with ${\mathrm{CHCl}}_3$?

Answer 1

1. When Benzene (${\mathrm{C}}_6{\mathrm{H}}_6$) reacts with Chloroform (${\mathrm{CHCl}}_3$) in presence of anhydrous Aluminum Chloride(${\mathrm{AlCl}}_3$) gives Triphenyl methane(${\left({\mathrm{C}}_6{\mathrm{H}}_5\right)}_3\mathrm{CH}$). This reaction is known as Friedel-Crafts Alkylation of Benzene.
2. Anhydrous Aluminum Chloride acts as a Lewis acid or catalyst which helps in the alkylation of benzene ring by attachment of Methyl group as it activates the alkyl halide.
3. This reaction involves an Electrophilic Substitution Reaction.
