Which instability arises when frontier molecular orbitals mix?

A)Jahn-Teller distortion occurs
B)Failing Aufbau principle alignment
C)Increased bandgap semiconductor resistivity
D)Eliminating singlet oxygen reactivity

💡 Explanation

The Jahn-Teller effect causes molecular distortion because unevenly filled degenerate orbitals reduce stabilization. This distortion lowers symmetry forming more stable (but lower symmetry) configurations, therefore lowering energy rather than conserving initial configurations.
