1 An aromatic molecule or compound is one that has special stability and properties due to a closed loop of electrons. 2  Not all molecules with ring (loop) structures are aromatic.3  A general scientific definition can be found below.or comparison, here are some molecules with ring structures that are not aromatic because they do not meet Hueckel'hÃ¼ckel S rule which requires that they have (2=n), 0 (6=n), 1 (10=n) 2 or (14=n) 3. etc-pi electrons in a: Ring MANY'pah s are extremely potent carcinogens or. mutagens
Aromatic compounds are substances that consist of one or more rings that contain alternating single and double bonds in its chemical structure. In real life, many aromatic compounds have an odor, there are some compounds that are chemically aromatic, but do not have a distinct smell.For example, benzene is an aromatic compound. The chemical structure of benzene, as illustrated below, contains a hexagon ring with alternating double bonds.uckel's Rule: Definition and Examples. Earlier, we saw that there are double bonds in the ring that is present in the chemical structure of aromatic compounds. These double bonds contain electrons called pi electrons.
