ChemistrySingle correct+4 / -1Question 40 of 90

In low and high spin octahedral Co $^{3+}$ complexes the number of electrons in t $_{2g}$ level respectively will be . (given At. no. of Co, 27)

6 and 3

6 and 4

3 and 4

4 and 6

Answer and worked solution

Official answer: B

Co³⁺ is $d^6$ . Low spin: $t_{2g}^6$ . High spin: $t_{2g}^4e_g^2$ . So 6 and 4.

(B)

Topics:Crystal field theory
