At first I read that an aromatic compound is a compound that contains a ring with alternating double bonds in which the electrons are delocalized and the ring exhibits a greater stability than regular conjugated systems. That makes sense to me. In Organic Chemistry by Clayden I read something different. In this book they say an aromatic compound is any compound that contains a benzene ring or other ring of atoms. Is that correct? If I'm not mistaken some rings have double bonds between their carbons and are not conjugated systems. Can an aromatic compound be a compound with a non conjugated ring system? In other words is any old cyclic compound considered an aromatic as long as it has a ring somewhere?
