    Which of the following complex ion will exhibit geometrical isomerism?

    A) \[{{[Cr\,{{({{H}_{2}}O)}_{4}}C{{l}_{2}}]}^{+}}\]

    B) \[[Pt\,{{(N{{H}_{3}})}_{3}}Cl]\]

    C) \[{{[Co\,{{(N{{H}_{3}})}_{6}}]}^{3+}}\]      

    D) \[{{[Co\,{{(CN)}_{5}}Cl]}^{3-}}\]

    Correct Answer: A

    Solution :

    [a]
    Octahedral complexes of the type \[[M{{A}_{4}}{{B}_{2}}]\] exhibit geometrical isomers.
    The type of complexes in the given options are as follows:           
    Complexes Types of complexes
    [a] \[{{[Cr\,{{({{H}_{2}}O)}_{4}}C{{l}_{2}}]}^{+}}\] \[[M{{A}_{4}}{{B}_{2}}]\]
    [b] \[[Pt\,{{(N{{H}_{3}})}_{3}}Cl]\] \[[M{{A}_{3}}B]\]
    [c] \[{{[Co\,{{(N{{H}_{3}})}_{6}}]}^{3+}}\] \[[M{{A}_{6}}]\]
    [d] \[{{[Co\,{{(CN)}_{5}}Cl]}^{3\,-}}\] \[[M{{A}_{5}}B]\]
    Hence, the given options only \[{{[Cr\,{{({{H}_{2}}O)}_{4}}C{{l}_{2}}]}^{+}}\]exhibit geometrical isomerism, cis and trans form.
