Crystal field splitting in octahedral complex -

e_{g} orbitals are more energetic as compared to t_{2g}

- wherein

 

 

CFSE in octahedral complex -

CFSE =\left [- \frac{2}{5}\left ( No. of\;electron\;in\;t_{2}g \right ) +\frac{3}{5}\left ( No. of\;\acute{e}s\;in\;eg \right ) \right ]\bigtriangleup \circ
