        Which of the following can participate in linkage isomerism?

    A)  \[NO_{2}^{-}\]                                

    B)  \[{{H}_{2}}\overset{\bullet \,\bullet }{\mathop{N}}\,C{{H}_{2}}C{{H}_{2}}\overset{\bullet \,\bullet }{\mathop{N}}\,{{H}_{2}}\]

    C)  \[H{{e}_{2}}\]                  

    D)  \[{}_{\bullet }^{\bullet }N{{H}_{3}}\]

    Correct Answer: A

    Solution :

                    \[NO_{2}^{-}\]a can participate in linkage isomerism because it may be bonded to metal through nitrogen or through oxygen. \[\underset{\begin{smallmatrix}  Pentaamminenitro \\  cobalt(III)\text{ }chloride \end{smallmatrix}}{\mathop{[{{(N{{H}_{3}})}_{5}}CoN{{O}_{2}}]C{{l}_{2}}}}\,\] and      \[\underset{\begin{smallmatrix}  Pentaamminenitro \\  cobalt\,(III)\text{ }chloride \end{smallmatrix}}{\mathop{[{{(N{{H}_{3}})}_{5}}CoONO]C{{l}_{2}}}}\,\]
