On the basis of crystal field theory the write the electronic configuration of d4 in terms of t2g and eg in an octahedral field , when (I) Δ0 > P (II) Δ0 < P |

Answer» If ∆o > P, it becomes more energetically favourable for the fourth electron to occupy a t2g orbital with configuration t2g4 eg0 . Ligands which produce this effect are known as strong field ligands and form low spin complexes. If ∆o < P. Ligands which produce this effect are known as strong field ligands and form low spin complexes. In this case the configuration is t2g3 eg1 |
