Question

Relative to the average energy in the spherical crystal field, the $t_{2g}$ orbitals in octahedral filed is :

• A. raised by $\left(2/5\right){\Delta }_{\circ }$
• B. lowered by $\left(2/5\right){\Delta }_{\circ }$
• C. raised by $\left(1/5\right){\Delta }_{\circ }$
• D. lowered by $\left(3/5\right){\Delta }_{\circ }$

Answer 1

The correct option is B lowered by $\left(2/5\right){\Delta }_{\circ }$

Relative to the average energy in the spherical crystal field, the $t_{2g}$ orbitals in octahedral filed is lowered by $\left(2/5\right){\Delta }_{\circ }$

Option (B) is correct.
