WebVolatility has nothing to do with stability. Benzene has six π electrons for its single aromatic ring. Its resonance energy is 36 kcal/6 electrons = 6.0 kcal/electron. Naphthalene has ten π electrons for its two aromatic rings. Its resonance energy is 61 kcal/10 electrons = 6.1 kcal/electron. Naphthalene has less resonance energy per ring ... WebSo, to qualify as an aromatic compound, the molecule needs to fit the following four criteria: First, the molecule must be cyclic. Which means, we’re looking for molecules with rings in them. The molecule must be planar. Or, in other words, the molecule must be flat. The molecule also must be fully conjugated.

WebAromatic compounds consist of compounds that are cyclic, possess a conjugated system, satisfy Huckel’s law, and are commonly planar. As the name suggests, cyclic structures form rings, as opposed to branching chain structures. Aside from a ring shape, aromaticity involves a continuous pi system.
