Identify the correct relationship correlating ligand field strength () with the principal quantum nu — Coordination Compounds Chemistry Question
Question
Identify the correct relationship correlating ligand field strength ($\Delta$) with the principal quantum number ($n$) of the transition metal's d-orbitals.
Answer: C
💡 Solution & Explanation
Heavier metals have more diffuse d-orbitals that interact more strongly with ligands. Thus, $\Delta$ increases significantly down a group: $3d < 4d < 5d$ [27, 53].
