The pair of coordination complexes//ion exhibiting the same kind of isomerism is (are) .

Options

A. a.`[Cr(NH_(3))_(5)Cl]Cl_(2)` and `[Cr(NH_(3))_(4)Cl_(2)]Cl`
B. b.`[Co(NH_(3))_(4)Cl_(2)]^(o+)` and `[Pt(NH_(3))_(2)(H_(2)O)Cl]^(o+)`
C. c.`[CoBr_(2)Cl_(2)]^(2-)` and `[PtBr_(2)Cl_(2)]^(2-)`
D. d.`[Pt(NH_(3))_(3)(NO_(3))]Cl` and `[Pt(NH_(3))_(3)Cl]Br`

Answer

b,d

Explanation

`[Co(NH_(3))_(4)CI_(2)]^(o+)` with `CN=6` is an octahedral complex) and
`[Pt(NH_(3))_(2)CI]^(o+)` with `CN =4` is a square planar complex both will show geometrical isomerism
(b) `[Pt(NH_(3))]CI` and `[Pt(NH_(3))_(3)CI]Br` will show ionisation isomerism .
