Solution
Correct Answer:
Aniline
The reduction of the nitro group (−NO2) to the amino group (−NH2) can be achieved through several methods:
- In Acidic Medium: Nitrobenzene is reduced using metals like Tin (Sn) or Iron (Fe) with concentrated HCl. Reaction: C6H5NO2+6[H]Sn/HClC6H5NH2+2H2O
- The product is Aniline.
- Iron scrap and HCl is preferred industrially because the generated FeCl2 is hydrolyzed to release HCl, thus only a small amount of acid is initiated for the whole process.
This easy difficulty chemistry question is from the chapter organic compounds containing nitrogen, covering the topic of nitro compounds. It appeared in the 2025 exam.
