Solution and Explanation
Weak field ligands induce minimal d-orbital splitting, preventing electron pairing. Consequently, complexes adopt a high-spin configuration with a greater number of unpaired electrons. Examples of weak field ligands include halides and water. Strong field ligands induce significant d-orbital splitting, leading to electron pairing and a low-spin configuration with fewer unpaired electrons. Examples of strong field ligands include CO and CN−.
