The coordination number, oxidation number, no. of d-electrons an dnumber of unpaired d-electrons on the metal are respectively:

Options

A. 6,3,6
B. 6,2,7
C. 5,3,6
D. 5,3,7

Answer

A

Explanation

`[overset(III)(Co)(NH_(3))_(4)CO_(3)]^(+)ClO_(4)^(-),CO_(3)^(-)` is working as bidentate ligand, have coordination number of `overset(III)(Co)=6`.
