In the presence of a strong octahedral ligand field, the number of unpaired electrons in Co(III)will be A) 0. B) 2. C) 4. D) 6. E) none of the above.

Question

Quizplus · Accepted Answer

In the presence of a strong octahedral ligand field, the electrons in the t2g orbitals (dxy, dyz, and dxz) experience a lower energy than the eg orbitals (dx2-y2 and dz2), resulting in electron pairing and no unpaired electrons. Therefore, the Co(III) complex will have all six electrons paired, resulting in zero unpaired electrons.
