Question

For producing amines, the reaction of nitro compounds with iron scrap is preferred because:

Options

• FeCl₂ is produced which undergo hydrolysis

• Nitro compounds are easily available

• Nitro compounds are easily available

• HCl is very cheap

Answer 1

FeCl₂ is produced which undergo hydrolysis

Explanation:

On reducing nitro compound by using scrap iron with HCl, FeCl₂ is produced which undergoes hydrolysis to produce HCl. Hence a small amount of HCl is required to initiate the reaction.

\[\ce{C6H5NO2 + 3Fe + 6HCl -> C6H5NH2 + 3FeCl2 + 2H2O}\]
