    Consider the following reaction.\[N{{O}_{2}}+NaOH\xrightarrow[{}]{{}}X+Y+{{H}_{2}}O\]. Which of the following statement is correct?

    A)  Both X and Y on treatment with Zn and NaON produce \[{{N}_{2}}\]

    B)  Both X and Y on heating with Na form \[{{N}_{2}}\]

    C)  Both [a] and [b] are correct

    D)  None of the above

    Correct Answer: C

    Solution :

     \[2N{{O}_{2}}+2NaOH\xrightarrow[{}]{{}}\underset{(X)}{\mathop{NaN{{O}_{3}}}}\,+\underset{(Y)}{\mathop{NaN{{O}_{2}}}}\,+{{H}_{2}}O\] \[2NaN{{O}_{3}}+10Na\xrightarrow[{}]{{}}6N{{a}_{2}}O+{{N}_{2}}\] \[NaN{{O}_{3}}+8H\xrightarrow[{}]{Zn/NaOH}NaOH+N{{H}_{3}}+2{{H}_{2}}O\]\[2NaN{{O}_{2}}+6Na\xrightarrow[{}]{{}}4N{{a}_{2}}O+{{N}_{2}}\] \[NaN{{O}_{2}}+6H\xrightarrow[{}]{{}}NaOH+N{{H}_{3}}+{{H}_{2}}O\]
