    Which of the following is isoelectronic with\[C{{O}_{2}}\]?

    A) \[N{{O}_{2}}\]                  

    B)         \[NO\]

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

    D)         \[{{N}_{2}}{{O}_{4}}\]

    E)  \[{{N}_{2}}{{O}_{5}}\]

    Correct Answer: C

    Solution :

    Isoelectronic species have equal number of electrons hence\[C{{O}_{2}}\]is isoelectronic with\[{{N}_{2}}O\] Number of electron in \[C{{O}_{2}}=22\] Number of electron in \[{{N}_{2}}O=22\]
