Discuss the nature of bonding in the following coordination entities on the basis of Valence Bond Theory : [Co(C_(2)O_(4))_(3))]^(3-) |
|
Answer» Solution :`[Co(C_(2)O_(4))_(3)]^(3-)` -- `d^(2)sp^(3)`, octahedral, diamagnetic. Formation of `[Co(C_(2)O_(4))_(3)]^(3-)` Oxidation state of Co is +3. Electronic configuration of `Co^(3+)` Pairing of ELECTRONS `d^(2)sp^(3)` hybridisation  Pairing of electrons TAKES place due to strong `C_(2)O_(4)^(2-)` ions `d^(2)sp^(3)` hybridisation takes place giving RISE to octahedral shape. As there are no unpaired electrons, the complex ion is diamagnetic. |
