Reduction of a nitro alkane with iron scrap (Fe) + HCl is preferred because ,

(i) Fe Cl₂ is produced which gets easily hydrolysed to form FeCl₃ and release HCl during the reaction.

Fe + 2HCl ------------> FeCl₂ + 2H

(ii) the process , therefore , becomes economical as only a small amount of HCl is required to initiate the reaction.

Usually(, Fe + HCl ) is preferred as a reducing agent , particularly in manufacture of amines.
