← ScienceWhich bond weakening occurs when UV photons strike ozone?
A)Antibonding orbital occupancy increases substantially✓
B)Hydrogen bonding begins in clustered molecules
C)Resonance structures become equally stable
D)Ionic character enhances molecular stability
💡 Explanation
UV striking zone causes **photoexcitation**. This excites electrons into antibonding orbitals, reducing the net bonding order; therefore, the bond weakens, destabilizing ozone, rather than increased stabilization via resonance due different molecular arrangements.
