Friedel Crafts Alkylation Part -02 and Friedel Crafts Acylation Reaction OF Benzene

Alkylation of aromatic compounds with aliphatic compounds like halides in presence of Lewis acid catalyst is known as Friedel-Crafts alkylation. It is an exapmle of electrophilic substitution. In the process of acylation, R-overset(O)overset(||)C- group is introduced to the ring. Compounds having ( + mesomeric groups) like -NH_(2) do not give Friedel-Crafts reaction because these compounds undergo conjugation with the catalyst. In the alkylation process, most branched alkyl group is substituted because isomerisation of carbonium ion takes place. In some Friedel-Crafts reactions, the nature of product changes with the solvent used in the reaction. Predict whether the following statements are ture or false: Following compounds easily give Friedel-Crafts reaction: (a) True (b) False

In some Friedel-Crafts reactions, the nature of product changes with the solvent used in the reaction. Predict whether the following statements are ture or false: Carbocations undergo isomerisation in Frieded-Crafts reaction. In each of the following alkyl halides the isomerisation takes place: CH_(3)-CH_(2)-CH_(2)-Cl , CH_(3)-CH_(2)-CH_(2)-CH_(2)-Cl (a) True (b) False
