    The complexes\[[PrC{{l}_{2}}{{(N{{H}_{3}})}_{4}}]B{{r}_{2}}\] 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. \[[PtC{{l}_{2}}{{(N{{H}_{3}})}_{4}}]B{{r}_{2}}\rightleftharpoons {{[PtC{{l}_{2}}{{(N{{H}_{3}})}_{4}}]}^{2+}}+2B{{r}^{-}}\]\[[PtB{{r}_{2}}{{(N{{H}_{3}})}_{4}}]C{{l}_{2}}\rightleftharpoons {{[PtB{{r}_{2}}{{(N{{H}_{3}})}_{4}}]}^{2+}}+2C{{l}^{-}}\]
