    The  complexes  \[[PtC{{l}_{2}}{{(N{{H}_{3}})}_{4}}]B{{r}_{2}}\]  and\[[PtB{{r}_{2}}{{(N{{H}_{3}})}_{4}}]C{{l}_{2}}\]  are   examples   for isomerism

    A) geometrical       

    B) optical

    C) ionisation           

    D) linkage

    Correct Answer: C

    Solution :

    Since the complexes \[[PtC{{l}_{2}}{{(N{{H}_{3}})}_{4}}]B{{r}_{2}}\] and \[[PtB{{r}_{2}}{{(N{{H}_{3}})}_{4}}]C{{l}_{2}}\]have the same molecular formula but on ionisation they give different ions, they exhibit ionisation isomerism. \[[PtC{{l}_{2}}{{(N{{H}_{3}})}_{4}}]B{{r}_{2}}{{[PtC{{l}_{2}}{{(N{{H}_{3}})}_{4}}]}^{2+}}+2B{{r}^{-}}\] \[[PtB{{r}_{2}}{{(N{{H}_{3}})}_{4}}]C{{l}_{2}}{{[PtB{{r}_{2}}{{(N{{H}_{3}})}_{4}}]}^{2+}}+2C{{l}^{-}}\]
