    A metal X on heating in nitrogen gas gives Y.Y on treatment with \[{{H}_{2}}O\] gives a colourless gas which when passed through \[CuS{{O}_{4}}\]solution gives a blue colour. Y is

    A) \[Mg{{(N{{O}_{3}})}_{2}}\]                      

    B) \[M{{g}_{3}}{{N}_{2}}\]

    C) \[N{{H}_{3}}\]                     

    D) \[MgO\]

    Correct Answer: B

    Solution :

    \[3\underset{X}{\mathop{Mx}}\,g+{{N}_{2}}\xrightarrow[{}]{\Delta }\underset{Y}{\mathop{M{{g}_{3}}}}\,{{N}_{2}};\]\[CuS{{O}_{4}}+4N{{H}_{3}}\xrightarrow[{}]{{}}[\underset{Blue\,complex}{\mathop{Cu{{(N{{H}_{3}})}_{4}}}}\,]S{{O}_{4}}\]
