    Production of nitrogen (I) oxide takes place by

    A) thermal decomposition of ammonium nitrate

    B) interaction of hydroxyl amine and nitric acid

    C) disproportionation of \[{{N}_{2}}{{O}_{4}}\]

    D) substitution of ammonium sulphate

    Correct Answer: A

    Solution :

    [a]
    The thermal decomposition of ammonium nitrate leads to formation of nitrogen (l) oxide.
    \[\underset{\begin{smallmatrix}  Ammonium \\  nitrate \end{smallmatrix}}{\mathop{N{{H}_{4}}}}\,N{{O}_{3}}\to \underset{\begin{smallmatrix}  Nitrogen\,(l) \\  Oxide \end{smallmatrix}}{\mathop{{{N}_{2}}O}}\,+\underset{Water}{\mathop{2{{H}_{2}}O}}\,\]
