  • question_answer
    The complex\[{{[Co{{(N{{H}_{3}})}_{5}}Br]}^{2+}}SO_{4}^{2-}\]and \[{{[Co{{(N{{H}_{3}})}_{5}}S{{O}_{4}}]}^{+}}B{{r}^{-}}\]are

    A)  coordination isomers

    B)  linkage isomers

    C)  stereoisomers

    D)  ionisation isomers

    Correct Answer: D

    Solution :

     The complexes\[{{[Co{{(N{{H}_{3}})}_{5}}Br]}^{2+}}SO_{4}^{2-}\]and \[{{[Co{{(N{{H}_{3}})}_{5}}S{{O}_{4}}]}^{+}}B{{r}^{-}}\]are ionization isomers. These can be distinguished by adding \[\text{BaC}{{\text{l}}_{\text{2}}}\]solution to the 1st complex which will give white ppt of\[\text{BaS}{{\text{O}}_{\text{4}}}\]and\[\text{AgN}{{\text{O}}_{\text{3}}}\]solution to 2nd complex which gives pale yellow ppt of AgBr.
