What compound is formed when hydrogen gas is passed through nitrobenzene in the presence of finely divided nickel?
Answer & explanation
Correct answer: option 2
The correct answer is option 2. Aniline.
When hydrogen gas is passed through nitrobenzene in the presence of finely divided nickel, the reaction that occurs is a catalytic hydrogenation. The nitro group \((-NO_2)\) in nitrobenzene \((C_6H_5NO_2)\) is reduced to an amino group \((-NH_2)\), resulting in the formation of aniline \((C_6H_5NH
In this process:
Nitrobenzene \((C_6H_5NO_2)\) is the starting material. Hydrogen gas \((H_2)\) is the reducing agent. Nickel (Ni) acts as the catalyst. Aniline \((C_6H_5NH_2)\) is the final product.
The reaction can be summarized as follows:
Therefore, the compound formed when hydrogen gas is passed through nitrobenzene in the presence of finely divided nickel is Aniline.
