On the basis of crystal field theory explain why Co(III) forms paramagnetic octahedral complex with weak field ligands whereas it forms diamagnetic octahedral complex with strong field ligands. |
| Answer» Solution :With WEAK field LIGANDS, `Delta_(0)ltP`. Electronic configuration of Co(III) will be `t_(2g)^(4)e_(G)^(2)`. Thus, it has 4 unpaired electrons and is PARAMAGNETIC. With strong field ligands, `Delta_(0)gtP`. Electronic configuration will be `t_(2g)^(6)e_(g)^(0)` has no unpaired electron and is diamagnetic. | |
