Give the significance of d^4 ions in octahedral field. |
|
Answer» <P> Solution :(i) If `Delta_0 LT P`, the `4^(TH)` electron enters into one of the `e_g` orbitals giving the configuration `t_2^3 e_g^1` . Ligands from which `Delta_0 lt P` are called weak field ligands. So they form HIGH spin complexes.(ii) If `Delta_0 gt P`, the `4^(th)` electron enters into `t_(2g)` orbitals giving the configuration `t_(2g)^4 e_g^0`. Ligands which produce this EFFECT are called strong field ligands. So they form low spin complexes. |
