Crystal field theory

Question

Crystal field splitting energy for high spin $d^{4}$ octahedral complex is

Moderate

A

$- 1.2 Δ_{o}$
B

$- 0.6 Δ_{o}$
C

$- 0.8 Δ_{o}$
D

$- 1.6 Δ_{o}$

Solution

$CFSE = (- 0.4 x + 0.6 y) Δ_{o} where, x = No. of electrons occupying t_{2 g} orbitals y = No. of electrons occupying e_{g} orbitals = (- 0.4 \times 3 + 0.6 \times 1) Δ_{o} [∵ High spin d^{4} = t_{2 g}^{3} e_{g}^{1}] = (- 1.2 + 0.6) Δ_{o} = - 0.6 Δ_{o}$
