    Which would exhibit ionisation isomerism [MP PET 1997]

    A) \[\left[ Cr{{\left( N{{H}_{3}} \right)}_{6}} \right]C{{l}_{3}}\]

    B) \[\left[ Co{{\left( N{{H}_{3}} \right)}_{5}}Br \right]S{{O}_{4}}\]

    C) \[\left[ Cr{{(en)}_{2}}C{{l}_{2}} \right]\]

    D) \[\left[ Cr{{(en)}_{3}}C{{l}_{3}} \right]\]

    Correct Answer: B

    Solution :

      The compound which has same composition but give different ions in solution, show ionization. So \[[Co{{(N{{H}_{3}})}_{5}}Br]\]\[SO_{4}^{{}}\]is ionization isomer. \[[Co{{(N{{H}_{3}})}_{5}}Br]S{{O}_{4}}\]⇌ \[{{[Co{{(N{{H}_{3}})}_{5}}Br]}^{2+}}+SO_{4}^{2-}\] \[[Co{{(N{{H}_{3}})}_{5}}S{{O}_{4}}]Br\]⇌ \[{{[Co(N{{H}_{3}})S{{O}_{4}}]}^{+}}+B{{r}^{-}}\].
