Solution

The nitro $(N O_{2})$ group of nitrobenzene is reduced to amino $(N H_{2})$ group by the replacement of two oxygens by two hydrogen to give aniline or benzenamine. Hence, the correct answer is option (a).

Q. Addition Reaction of Ethene with Hydrogen "In presence of finely divided platinum or palladium or Raney nickel, the reaction takes place at room temperature. In presence of nickel catalyst, the reaction takes place at 200-300°C." Does this mean : If we use nickel catalyst and we provide a temperature of 200-300°C then the reaction will take place. But if we use finely divided platinum or palladium or Raney nickel, the reaction would take place at room temperature, that is, no extra amount of heat needs to be given. Thus, it is more convenient to use finely divided platinum or palladium or Raney nickel than Nickel+extra heat. But why is Ni generally mentioned to be more convenient?
