    Which of the following compound would exhibit co-ordination isomerism?

    A)  \[[Cr{{(en)}_{2}}]\,N{{O}_{2}}\]

    B)  \[[Cr{{({{H}_{2}}O)}_{6}}]\,C{{l}_{3}}\]

    C)  \[[Cr{{(N{{H}_{3}})}_{6}}]\,\,[Co{{(CN)}_{6}}]\]

    D)  None of the above

    Correct Answer: C

    Solution :

    The isomerism, in which there is an exchange between groups of co-ordination sphere of one complex ion and group of co-ordination sphere of other ion, is called co-ordination isomerism. \[[Cr{{(N{{H}_{3}})}_{6}}]\,\,[Co{{(CN)}_{6}}]\] and        \[[Co{{(N{{H}_{3}})}_{6}}]\,\,[Cr{{(CN)}_{6}}]\]
