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 WebIn this explainer, we will learn how to describe addition and substitution reactions of benzene and predict what products are formed. Benzene is a small aromatic hydrocarbon. It is volatile (boiling point: 8 0. 1 ∘ C) and carcinogenic and burns with a very sooty flame. Benzene ( C H 6 6) is the most common example of an aromatic system.
