Why is the reduction of nitro compounds with iron scrap and hydrochloric acid preferred?

Options

  1. AIron scrap is cheaper than other metals.
  2. BIron scrap catalyses the reaction.
  3. CHydrochloric acid is not required in this method.
  4. DIron scrap forms FeCl 2 , which is a strong reducing agent.

Correct answer

B. Iron scrap catalyses the reaction.

Step-by-step solution

Iron scrap catalyses the reduction reaction, and FeCl 2 formed during the reaction helps in initiating the reaction, making it efficient. This reduces the amount of hydrochloric acid required.
