The substitution of a '-H' by '-NO2' group in benzene is called:
Correct answer: A. Nitration
- A. Nitration
- B. Ammonolysis
- C. Sulphonation
- D. Reduction of benzene
Explanation
Nitration reactions are the addition of a nitro group into an organic compound. So addition of NO2 group in a benzene ring would also be a nitration reaction.

About Benzene and Aromatic Compounds
Benzene has a planar ring of delocalised π electrons, giving aromatic stability and equal carbon-carbon bond lengths. The topic covers resonance, electrophilic substitution reactions such as nitration, halogenation, sulphonation and Friedel-Crafts reactions, along with substituent effects and the distinction between substitution in benzene and addition in ordinary alkenes.
