Statement 1 : Fe + HCI is preferred as a reagent in the oxidation of nitroalkanes to alkanamines.Statement 2 : Iron scrap and HCI is preferred in the reduction reaction of nitrobenzene.

Reduction of nitro compounds with Fe scrap and HCI is : preferred because FeCl2 formed gets hydrolysed to release HCl during the reaction.Thus, only a small amount of HCl is required to initiate the reaction.
