Among complexes [Fe(H_(2)O)_(6))]^(3+)", [Fe(CN)_(6)]^(3-). [Fe(C_(2)O_(4))]^(3-), more stability is shown by

Answer»

`[Fe(H_(2)O)_(6)]^(3+)`
 `[Fe(CN)_(6)]^(2-)` 
`[Fe(P_(2)O_(4))_(3)]^(3-)`.
`[Fe(CI)_(6)]^(3-)`

Solution :Complex having more rings in structure will be more stable. Hence, (C) is the CORRECT answer.
