write the mechanism of benzene
Halogenation, nitration, sulfonation, alkylation, acylation are various electrophilic substitution reactions of benzene thus forming a monosubstitued benzene as the only product in the presence of a catalyst.Halogenation:Benzene forms bromobenzene or chlorobenzene while reacting with chlorine or bromine in the presence of Lewis acids like AlCl3 , FeCl3, FeBr3, etc.Nitration:Nitrobenze is formed when benzene is treated with fuming nitric acid. Sulphuric acid is the catalyst help in generation, that is nitronium ion.Friedel-Crafts Alkylation:Alkylbenzenes are formed by benzene when it reacts with haloalkanes in the presence of a Lewis acid.Thanks & Regards,Vasantha Sivaraj,askIITians faculty
