Chemical Bonding & Molecular Structure
Dimensionless
The description of a molecule whose true structure is a weighted average of two or more valid Lewis structures.
A ↔ B ↔ C
Resonance Energy
Chemical Bonding & Molecular Structure
kJ/mol
The extra stability a molecule gains from electron delocalisation, measured against the most stable single Lewis structure.
ΔE_res = E(hybrid) − E(best structure)
