Friedel-Crafts Alkylation

The video tutorial explains the Friedel-Crafts alkylation process, highlighting its similarity to halogenation. It details the formation of a catalytic intermediate using aluminum trichloride, the cleavage of the carbon-chlorine bond to form a carbocation, and the subsequent reaction with a benzene ring. The process concludes with the restoration of aromaticity and regeneration of the catalyst.

What is the significance of restoring aromaticity in the Friedel Crafts alkylation mechanism?

Explain the difference between the Friedel Crafts alkylation and the halogenation mechanism.
