Which instability arises when frontier molecular orbitals mix?

💡 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.
