The splitting of d orbital in the bonding is called:
Correct answer: C. d-d splitting
- A. Quantum Leap
- B. Orbital delocalization
- C. d-d splitting
- D. d-d splitting and orbital delocalization
Explanation
When the ligands approach the central metal ion, d- or f-subshell degeneracy is broken due to the static electric field. Because electrons repel each other, the d electrons closer to the ligands will have a higher energy than those further away, resulting in the d orbitals splitting. This is called d-d splitting.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
