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

    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 :

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