    An octahedral complex with molecular composition M.5 \[N{{H}_{3}}.Cl.S{{O}_{4}}\] has two isomers, A and B. The solution of A gives a white precipitate with \[AgN{{O}_{3}}\] solution and the solution of B gives white precipitate with \[BaC{{l}_{2}}\] solution. The type of isomerism exhibited by the complex is:   

    A) Linkage isomerism

    B) lonisation isomerism

    C) Coordinate isomerism

    D) Geometrical isomerism

    Correct Answer: B

    Solution :

    [b] The two possible isomers for the given octahedral complex are \[[M{{(N{{H}_{3}})}_{5}}S{{O}_{4}}]Cl\] and \[[M{{(N{{H}_{3}})}_{5}}Cl]\,S{{O}_{4}}\]. They respectively give chloride ion (indicated by precipitation with\[BaC{{l}_{2}}\]) and \[S{{O}_{4}}\] ion (indicated by precipitation with\[AgN{{O}_{3}}\]). Hence the type of isomerism exhibited by the complex is ionization isomerism.
