Which ion would you expect to have the largest crystal field splitting,△? A)[Rh(CN)₆]^4- B)[Rh(CN)₆]^3- C)[Rh(H₂O)₆]²⁺ D)[Rh(H₂O)₆]³⁺

Question

Quizplus · Accepted Answer

The crystal field splitting, Δ, is influenced by the nature of the ligands surrounding the metal ion, with stronger field ligands causing larger splitting. Cyanide (CN-) is a strong field ligand, leading to a larger Δ. Among the options, [Rh(CN)₆]³⁻ (option B) has six cyanide ligands, which would result in the largest crystal field splitting due to the strong field nature of cyanide ligands and the octahedral geometry.
