alkylation and acylation of benzene

• alkylation of benzene


  substitution of an H atom in benzene ring with an alkyl groupe.g methyl ($CH_3$), ethyl ($C2H_5$)
• acylation of benzene


  substitution of an H atom in benzene ring with acyl group e.g ethanoyl (CH3CO), propanoyl (CH3CH2CO)
• both acylation and alkylation involve electrophilic substitution
• both acylation and alkylation reactions involve the halogen carrier catalyst AlCl3
• both acylation and alkylation called friedel-crafts reactions
• both acylation and alkylation increase the number of carbon atoms in the structure
