Identify the product obtained when nitro alkanes are treated with...

Nitro alkanes are reduced to primary amines when treated with a mixture of tin and hydrochloric acid (Sn/HCl). The reaction involves the reduction of the nitro group ($-\text{NO}_2$) to an amino group ($-\text{NH}_2$).

$\text{R-NO}_2 + 6[\text{H}] \xrightarrow{\text{Sn/HCl}} \text{R-NH}_2 + 2\text{H}_2\text{O}$

Thus, the product obtained is a primary amine, $\text{R-NH}_2$.

Answer: $\text{R-NH}_2$
