Explain the following : [Co(NH_(3))_(6)]^(3+) is diamagnetic, whereas [CoF_(6)]^(3-) is paramagnetic. |
| Answer» SOLUTION :`[Co(NH_(3))_(6)]^(3+)` is diamagnetic because `NH_(3)` is STRONG field LIGAND. It causes pairing of ELECTRONS and no unpaired electrons are left. `[CoF_(6)]^(3-)` is paramagnetic because `F^(-)` is weak field ligand. It does not cause pairing of electrons and there are unpaired electrons left. | |
