Draw a sketch to show the splitting of d-orbitals in an octahedral crystal field. State for a d^(6) configuration, how the actual configuration of the split d-orbitals in an octahedral crystal field is decided by the relative values of Delta_(0) and P ? |

Answer» Solution :Splitting of d-orbitals in an octahedral field. For `d^(6)` configuration, three electrons will first enter into `t_(2g)`. Now, if `P lt Delta_(0)`, electrons will PAIR up in `t_(2g)` orbitals, giving the configuration `t_(2g)^(6)` and if `Delta_(0)ltP`, two electrons will first enter into `e_(g)` orbitals and one will pair up in `t_(2g)` giving the configuration `t_(2g)^(4) e_(g)^(2)`. |
