Question

Nitrogen (I) oxide is produced by

• A. thermal decomposition of $NH_4NO_3$
• B. disproportionation of $N_2O_4$
• C. thermal decomposition of $NH_4NO_2$
• D. interaction of hydroxylamine and nitrous acid

Answer 1

Answer: (D)

interaction of hydroxylamine and nitrous acid

Answer 2

$NH_4NO_3 \xrightarrow{Heat} N_2O + 2H_2O$ $NH_2OH - HCl + NaNO_2 \longrightarrow NaCl + 2H_2O + N_2O$ However, $NH_4N O_2$ on heating gives $N_2$
