Directions : In the following question more than one of the answers given may be correct. Select the correct answer and mark it according to the code:
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 nitriteA) 1, 2 and 3 are correct
B) 1 and 2 are correct
C) 2 and 4 are correct
D) 1 and 3 are correct
Correct Answer: D
Solution :
(1) \[\underset{\begin{smallmatrix} ammonium \\ \,\,\,\,\,nitrate \end{smallmatrix}}{\mathop{N{{H}_{4}}N{{O}_{3}}}}\,\xrightarrow{\Delta }\underset{\begin{smallmatrix} \,\,\,\,\,\,nitrogen\text{ }(I) \\ oxide\text{ }or\text{ }nitrous \\ \,\,\,\,\,\,\,oxide \end{smallmatrix}}{\mathop{{{N}_{2}}O}}\,+2{{H}_{2}}O\] (2) \[{{N}_{2}}{{O}_{4}}+{{H}_{2}}O\xrightarrow[{}]{Disproportionation}HN{{O}_{2}}\] \[+HN{{O}_{3}}\] (3) \[\underset{\begin{smallmatrix} hydroxyl \\ \,\,\,\,\,a\min e \end{smallmatrix}}{\mathop{N{{H}_{2}}OH}}\,+\underset{nitrous\text{ }acid}{\mathop{HN{{O}_{2}}}}\,\to \underset{\begin{smallmatrix} nitrous \\ \,\,oxide \end{smallmatrix}}{\mathop{{{N}_{2}}O}}\,+2{{H}_{2}}O\] (4) \[\underset{ammonium\text{ }nitrite}{\mathop{N{{H}_{4}}N{{O}_{2}}}}\,\xrightarrow{\Delta }{{N}_{2}}+2{{H}_{2}}O\]
