    The pair of \[[Co(S{{O}_{4}}){{(N{{H}_{3}})}_{5}}]\,Cl\]and\[[CoCl(N{{H}_{3}}){{(N{{H}_{3}})}_{5}}]\,S{{O}_{4}}\] constitutes

    A)  optical isomers

    B)  linkage isomers

    C)  coordination isomers

    D)  hydrate isomers

    E)  ionisation isomers

    Correct Answer: E

    Solution :

                    \[[Co(S{{O}_{4}})\,{{(N{{H}_{3}})}_{5}}]\,Cl\rightleftharpoons {{[Co(S{{O}_{4}}){{(N{{H}_{3}})}_{5}}]}^{+}}+C{{l}^{-}}\]\[[CoCl\,{{(N{{H}_{3}})}_{5}}]\,S{{O}_{4}}\rightleftharpoons {{[CoCl{{(N{{H}_{3}})}_{5}}]}^{2+}}+SO_{4}^{2-}\] These complexes give different ions when subjected to ionisation. So, they exhibit ionisation isomerism.
