NITRATIONThe addition of nitrile group (NO2) in any organic compound is called nitration of organic compounds.

NITRATION OF BENZENE•The addition of nitrile group in benzene ring is called nitration of benzene.•The nitration of benzene is carried out in the presense of conc.H2SO4 at 50-55 C Temprature.

REACTION•The nitric acid react with benzene in the presence of conc.H2SO4 at 50 c temprature and produced Nitrobenzene with the elimination of water.

MECHANISM• In mechanism of nitration of benzene we first took 1:1 of Conc.H2SO4 and Conc.HNO3

and react them at 50-55 c temperature.•The resulting product is produced Nitronium Ion plus Hydro Sulphate Ion plus Water.

• The nitronium ion first react with benzene at 50 c and this reaction is slow.Then Hydro Sulphate react and this reaction is fast and produced Nitrobenzene with elimination of H2SO4.
