← ScienceWhich effect arises when applying an external magnetic field on valence orbitals?
A)Zeeman splitting reduces orbital degeneracy✓
B)Increased metallic bond electron delocalization
C)Crystal field accelerates orbital hybridization
D)Resonance destabilization expands frontier orbitals
💡 Explanation
Zeeman splitting lifts the degeneracy of atomic orbitals because the interaction of the electron's magnetic moment with the external field introduces energy differences; therefore orbitals split, rather than hybridizing because crystal field deal with ionic lattices.
