    Which one of the following octahedral complexes will not show geometric isomerism? (A and B are monodentate ligands)

    A) \[[M{{A}_{5}}B]\]

    B) \[[M{{A}_{2}}{{B}_{4}}]\]

    C) \[[M{{A}_{3}}{{B}_{3}}]\]

    D) \[[M{{A}_{4}}B{{ }_{2}}]\]

    Correct Answer: A

    Solution :

    \[M{{A}_{3}}{{B}_{3}}-2\]geometrical isomers
    \[M{{A}_{2}}{{B}_{4}}-2\]geometrical isomers
    \[M{{A}_{4}}{{B}_{2}}-2\]geometrical isomers
    The complex of general formula \[M{{A}_{6}}\] and \[M{{A}_{5}}B\]having octahedral geometry do not show geometrical isomerism.
