The sum of coordination number and oxidation number of the metal M in the complex `[M(en)_(2) (C_(2)O_(4))]Cl` (where en is ethylenediamine) is:

A

7

B

8

C

9

D

6

Text Solution

Verified by Experts

The correct Answer is:
C
`[M(en)_(2)(C_(2)O_(4))]Cl`
x+0-2-2-1=0
x=+2+1
x=+3
en, and `C_(2)O_(4)^(2-)` are bidentate ligand.

Coordination no=6
sum of coordination no and oxidation no.
6+3=9
