Freidel-Crafts Acylation

The video tutorial explains Freidel-Crafts acylation, a process similar to alkylation, involving benzene, acyl chloride, and aluminum trichloride catalyst. It details the mechanism, formation of acylium ion, and regeneration of the catalyst. The acylation product is meta-directing and deactivating due to electron withdrawal.

What is the significance of the resonance structures in the acylium ion during the reaction?

What byproduct is formed during the Freidel-Crafts acylation reaction, and why is it important?

How does the acyl group affect the reactivity of the product in further electrophilic aromatic substitution reactions?
