1.

The pair(s) of coordination complexes/ions exhibiting the same kind of isomerism is(are)

Answer»

`[Cr(NH_(3))_(5)Cl]Cl_(2)` and `[Cr(NH_(3))_(4)Cl_(2)]Cl`
`[Co(NH_(3))_(4)Cl_(2)]^(+) and [Pt(NH_(3))_(2)(H_(2)O)Cl]^(-)`
`[CoBr_(2)Cl_(2)]^(2-) and [PtBr_(2)Cl_(2)]^(2-)`
`[Pt(NH_(3))_(3)(NO_(3))]Cl and [Pt(NH_(3))_(3)Cl]Br`

SOLUTION :Each complex ion in the pair `[Co(NH_(3))_(4)Cl_(2)]^(+),[Pt(NH_(3))_(2)(H_(2)O)Cl]^(-)` shows geometrical isomerism. Each complex in the pair `[Pt(NH_(3))_(3)(NO_(3))]Cl,[Pt(NH_(3))_(3)Cl]Br` shows ionization isomerism. In other pairs, the two complexes/ions do not show the same type of isomerism.
