Question

Nitrogen (I) oxide is produced by
(1) thermal decomposition of ammonium nitrate
(2) disproportionation of $N_2{O}_4$
(3) interaction of hydroxyl. amine and nitrous acid
(4) thermal decomposition of ammonium nitrite

• A. 1, 2 and 3 are correct
• B. 1 and 2 are correct
• C. 2 and 4 are correct
• D. 1 and 3 are correct

Answer 1

Answer: (D)

(1) $\underset{\text{ammonium nitrate}}{N{H}_{4}N{O}_3}\stackrel{\Delta }{\to }\underset{\text{nitrogen (I) oxide or nitrous oxide}}{N_{2}O}+2H_{2}O$
(2) $N_2{O}_4+H_{2}O\stackrel{\text{ Disproportionation }}{\to }HN{O}_2+HN{O}_3$
(3) $\underset{\text{hydroxyl amine}}{N{H}_{2}OH}+\underset{\text{nitrous acid}}{HN{O}_2}\to \underset{\text{nitrous oxide}}{N_{2}O}+2H_{2}O$
(4) $\underset{\text{ammonium nitrite}}{N{H}_{4}N{O}_2}\stackrel{\Delta }{\to }{N}_2+2H_{2}O$
