Question

The pair of coordination complex exhibiting the same kind of isomerism is .
A. `[Cr(NH_(3))_(5)Cl]Cl_(2)` and `[Cr(NH_(3))_(4)Cl_(2)]Cl`
B. `[Co(NH_(3))_(4)Cl_(2)]^(2+)` and `[Pt(NH_(3))_(2)(H_(2)O)Cl]^(+)`
C. `[CoBr_(2)Cl_(2)]^(2-)` and `[PtBr_(2)Cl_(2)]^(2-)`
D. `[Pt(NH_(3))_(3)(NO_(3))]Cl` and `[Pt(NH_(3))_(3)Cl]Br`

Answer 1

Correct Answer - b,d
(b,d) The complex `[Co(NH_3)_4Cl_2]^(+)` and `[Pt(NH_3)_2(H_(2)O)Cl^(-)` both exhibit geometrical isomerism (b) .
The complex `[Pt(NH_3)_3(NO_3)CL] ` and `[Pt(NH_3)Cl]Br` both exhibit ionisation isomerism (d) .
