Definitions:

Energy π MO

Refers to molecular orbitals formed by the overlap of pi orbitals, affecting molecular stability and reactivity, particularly in conjugated systems.

Resonance Energy

The difference in energy between the actual structure of a molecule and the energy of the most stable resonance structure, indicating stability due to resonance.

Stability

The tendency of a chemical compound to maintain its original state or resist decomposition under specific conditions.

S-trans Conformation
