    Which among the following statements are true for the complex\[[Co{{(N{{H}_{3}})}_{6}}][Cr{{(CN)}_{6}}]\]?
    1. It is a non-electrolyte
    2. The magnitude of the charge on each complex ion is 3
    3. The complex will not conduct current
    4. The complex will exhibit coordination isomerism
    5. The magnitude of the charge on each complex ion is 1

    A)  1 and 4                                

    B)  1 and 2

    C)  1 and 3                

    D)         3 and 5

    E)  2 and 4

    Correct Answer: E

    Solution :

    \[{{[Co{{(N{{H}_{3}})}_{6}}]}^{3+}}{{[Cr{{(CN)}_{6}}]}^{3-}}\] Coordination isomer of complex: \[{{[Cr{{(N{{H}_{3}})}_{6}}]}^{3+}}{{[Co{{(CN)}_{6}}]}^{3-}}\]
