  • question_answer
    Consider the following sequence of reaction. \[Na+N{{H}_{3}}\left( g \right)\xrightarrow{{}}\left[ X \right]\xrightarrow{{{N}_{2}}O}\] \[\left[ Y \right]\xrightarrow{Heat}\underset{Gas\,Pure}{\mathop{\left[ Z \right]}}\,\] Identify (Z) gas:

    A) \[{{N}_{2}}\]               

    B) \[N{{H}_{3}}\] 

    C) \[{{O}_{2}}\]                           

    D) \[{{H}_{2}}\]

    Correct Answer: A

    Solution :

    [a] \[Na+N{{H}_{3}}(g)\xrightarrow{\Delta }\underset{[X]}{\mathop{NaN{{H}_{2}}}}\,\] \[\xrightarrow{{{N}_{2}}O}\underset{[Y]}{\mathop{Na{{N}_{3}}}}\,\xrightarrow{\Delta }\underset{[Z]}{\mathop{{{N}_{2}}}}\,\uparrow \]
