(A) Friedel-Crafts Alkylation:
Reaction: Benzene + Methyl chloride \((CH_3Cl)\) in the presence of anhydrous \(AlCl_3\) as a catalyst.
Product: Toluene (Methylbenzene).
\(C_6H_6 + CH_3Cl \xrightarrow{AlCl_3}C_6H_5CH_3 + HCl\)
(B) Friedel-Crafts Acylation:
Reaction: Benzene + Acetyl chloride \((CH_3 COCI)\) in the presence of anhydrous \(AlCl_3\) as a catalyst.
Product: Acetophenone (Phenyl methyl ketone).
\(C_6H_6 + CH_3COCl\xrightarrow{AlCl_3}C_6H_5COCH_3 + HCl\)
