    Which one of the following octahedral complexes will not show geometrical isomerism? (A and B are monodentate ligands)              [AIPMT 2003]

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

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

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

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

    Correct Answer: B

    Solution :

    [b] \[[M{{A}_{5}}B]\]due to absence of symmetry of 'B' ligand cannot exist in the form of cis-trans isomer.
