← ScienceWhich mechanism causes increased molecule reactivity when ligands occupy antibonding orbitals?
A)Crystal field stabilization energy increase
B)Increased frontier orbital energy levels✓
C)Enhanced intersystem crossing probability
D)Decreased nuclear magnetic resonance shielding
💡 Explanation
Molecule reactivity with antibonding orbital occupation increases due to **antibonding destabilization**, because electrons populate higher-energy antibonding orbitals. Therefore, the HOMO rises, promoting easier electron donation rather than alternative stabilization effects near lower bonding energies.
