High stability of benzene is explained by
WebLike benzene, the conjugated diene systems show increased stability. Because of resonance, the benzene molecule is more stable than its 1,3,5‐cyclohexatriene structure suggests. This extra stability (36 kcal/mole) is referred to as its resonance energy. Orbital picture of benzene WebApr 15, 2024 · As shown in Supplementary Fig. 4, the benzene-water potential energy scan exhibits a binding energy of ~2 kcal/mol when the water molecule point one of the OH bond towards the aromatic ring, which ...
