Answer 2

Transformation of Acetylene to Aniline

To transform acetylene into aniline, we can follow the following steps:

1. Acetylene to Benzene: - Acetylene can be converted to benzene through a process called hydrogenation. This involves the addition of hydrogen in the presence of a suitable catalyst. - The chemical equation for this reaction is: ``` 3C2H2 → C6H6 ```

2. Benzene to Nitrobenzene: - Benzene can be converted to nitrobenzene through a nitration reaction, which involves the addition of a nitro group (NO2) to the benzene ring in the presence of a nitrating agent, such as concentrated nitric acid (HNO3) and sulfuric acid (H2SO4). - The chemical equation for this reaction is: ``` C6H6 + HNO3 → C6H5NO2 + H2O ```

3. Nitrobenzene to Aniline: - Nitrobenzene can be converted to aniline through a reduction reaction, which involves the removal of the nitro group and the addition of hydrogen to the benzene ring in the presence of a reducing agent, such as iron and hydrochloric acid. - The chemical equation for this reaction is: ``` C6H5NO2 + 3H2 → C6H5NH2 + 2H2O ```

4. TriBromoAniline: - TriBromoAniline can be obtained by the bromination of Aniline. The chemical equation for this reaction is: ``` C6H5NH2 + 3Br2 → C6H2Br3NH2 + 3HBr ```

By following these steps, we can successfully transform acetylene into tribromoaniline.
