Question

In a high spin octahedral complex, the $d^7$ configuration according to CFT is

• A. $t_{2g}^6,e^{1}g$
• B. $t_{2g}^4,e^{3}g$
• C. $t_{2g}^3,e^{4}g$
• D. $t_{2g}^5,e^{2}g$

Answer 1

The correct option is D $t_{2g}^5,e^{2}g$

High spin complex means ligand is weak, hence, ${\Delta }_0$ < P (pairing energy)
