Question

Relative to the average energy in the spherical crystal field, the $e^g$ orbitals in tetrahedral field is:

• A. raised by $\left(2/5\right){\Delta }_t$
• B. lowered by $\left(4/5\right){\Delta }_t$
• C. raised by $\left(3/5\right){\Delta }_t$
• D. lowered by $\left(3/5\right){\Delta }_t$

Answer 1

The correct option is D lowered by $\left(3/5\right){\Delta }_t$

$e_g$ orbitals have lower energies by $\left(3/5\right){\Delta }_t$ with respect to average energy.
