Which of the following ligands is responsible for the largest d orbital splitting?
A) CN−
B) F−
C) Cl−
D) H2O
E) NH3

Question

Quizplus · Accepted Answer

CN− is a strong field ligand, which means it causes a large d orbital splitting. This is because CN− has a high negative charge, which attracts the electrons in the d orbitals of the metal ion. This attraction causes the d orbitals to split into two sets, with the lower energy set being occupied by the electrons.
