Which of the following complexes has the smallest crystal field splitting of the d orbitals? A)CoF₆³ B)Co(CN)₆^3- C)CoBr₆^3-- D)Co(H₂O)₆³⁺ E)CoI₆^3-

Question

Quizplus · Accepted Answer

The crystal field splitting depends on the ligands surrounding the central metal ion. In general, stronger ligands such as CN- or F- lead to a larger splitting of the d orbitals, while weaker ligands such as I- or Br- lead to a smaller splitting. Among the given options, CoI6 has the weakest ligands and therefore the smallest crystal field splitting of the d orbitals.
