Discuss the nature of bonding in the following coordination entities on the basis of Valence Bond Theory : [FeF_(6)]^(3-) |
|
Answer» Solution :`[FeF_(6)]^(3-)` -- `SP^(3)d^(2)`, octahedral, paramagnetic. Formation of `[FeF_(6)]^(3-)` Oxidation state of Fe in the complex is +3. Electronic configuration of `Fe^(3+)` No pairing of electrons `sp^(3)d^(2)` HYBRIDISATION of orbitals  As P- ions are weak ligands, no pairing takes place, outer complex with `sp^(3)d^(2)` hybridisation (octahedral) is formed. As there are 5 unpaired electrons, the complex is paramagnetic. |
