Coordination Compounds

Question
CBSEENCH12007373
Wired Faculty App

If the value of Δ0 is less than P in the crystal field, write the arrangement of d4coordination entity in crystal field split.

Solution
If Δ0 < P, the weak field and high spin situation is present, thus no pairing will occur in t2g orbitals. Hence the configuration of d4 entity will be t2g3 eg1
