    In Ramsay and Rayleigh's isolation of noble gases from air, the nitrogen of the air is finally converted into

    A)  \[NaN{{O}_{2}}\]only

    B)  NO and \[N{{O}_{2}}\]

    C)                  \[NaN{{O}_{3}}\] only

    D)  \[NaN{{O}_{2}}\] and \[NaN{{O}_{3}}\]

    Correct Answer: D

    Solution :

    In Ramsay and Rayleigh's isolation of noble gases from air, the nitrogen of the air finally converted into \[NaN{{O}_{2}}\] and \[NaN{{O}_{3}}\].                 \[{{N}_{2}}+{{O}_{2}}\xrightarrow{\begin{smallmatrix}  Electric \\  discharge \end{smallmatrix}}2NO\]                 \[{{N}_{2}}+{{O}_{2}}\xrightarrow{{}}2N{{O}_{2}}(g)\] \[2N{{O}_{2}}+2NaOH\xrightarrow{{}}NaN{{O}_{2}}+NaN{{O}_{3}}+{{H}_{2}}O\]
