							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.
