Identify the product obtained when nitro alkanes are treated with Sn / HCl.
- Correct answerA$\text{R-NH}_2$
- B$\text{R}_2\text{NH}$
- C$\text{R}_3\text{N}$
- D$\text{R}_4\text{N}^+\text{X}^-$
Solution
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: $\text{R-NH}_2$
$\text{R-NO}_2 + 6[\text{H}] \xrightarrow{\text{Sn/HCl}} \text{R-NH}_2 + 2\text{H}_2\text{O}$
Thus, the product obtained is a primary amine, $\text{R-NH}_2$.
Answer: $\text{R-NH}_2$
Hence, the correct answer is option: 'A'.
