Nitration of benzene !

I hope You all like it. I hope It is very beneficial for you all. I really thought that you all get enough knowledge from this presentation. This presentation is about materials and their classifications. After you read this presentation you knowledge is not as before.

3. nitration The addition of nitrile group (NO 2 ) in any organic compound is called nitration of organic compounds.

4. 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.H 2 SO 4 at 50-55 C Temprature .

5. reaction The nitric acid react with benzene in the presence of conc.H 2 SO 4 at 50 c temprature and produced Nitrobenzene with the elimination of water.

6. mechanism In mechanism of nitration of benzene we first took 1:1 of Conc.H 2 SO 4 and Conc.HNO 3 and react them at 50-55 c temperature. The resulting product is produced Nitronium Ion plus Hydro Sulphate Ion plus Water.

7. 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 H 2 SO 4.
