Introduction of nitro group in a molecule is called___________________?
Correct answer: A. nitration
- A. nitration
- B. halogenation
- C. sulphonation
- D. amination
Explanation
Nitration is the introduction of a nitro group, -NO2, into an organic molecule, commonly by treating an aromatic compound with concentrated nitric and sulfuric acids. The likely mistake is choosing amination, but amination introduces an amino group, -NH2, not a nitro group.

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.
