[Fe(CN)_(6)]^(4-) and [Fe(H_(2)O)_(8)]^(2+) are of different colours in dilute solutions. Why |
| Answer» Solution :In both the complexes, `Fe is in +2` state with the configuration `3d^(6)`, i.e., it has FOUR unpaired electrons. As the ligands `H_(2)O and.`CN^(-)` posses, different CRYSTAL FIELD splitting energy(triangle_(o))`, they absorb different components of the visible light (VIBGYOR) for d-d TRANSITION. HENCE, the transmitted colours are different | |
