Amongst the following, the most stable complex is -

A

`[Fe(H_(2)O)_(6)]^(3+)`

B

`[Fe(NH_(3))_(6)]^(3+)`

C

`[Fe(C_(2)O_(4))_(3)]^(3-)`

D

`[FeCl_(6)]^(3-)`

Text Solution

Verified by Experts

The correct Answer is:
C
`[Fe(C_(2)O_(4))_(3)]^(3-)` is the most stable complex ion due to chelate formation as `C_(2)O_(4)^(2-)` is a bidentate chelating ligand.
