Regarding the preparation of amines by the reduction of nitro compounds, which of the following stat — Amines Chemistry Question

💡 Solution & Explanation

Statements A, B, and C correctly detail standard reduction methodologies for the $-NO_2$ group. Scrap iron is the preferred industrial reagent specifically due to the cyclic regeneration of $HCl$, making it highly cost-effective. Statement D is unequivocally false because the reduction of nitroalkanes cleanly yields pure primary amines ($R-NO_2 \rightarrow R-NH_2$), not a secondary/tertiary mixture.
