Benzene Ring model Molecule model of Benzene with its ring formed structure. benzene rings stock pictures, royalty-free photos & images Anthranilic acid molecular structure isolated on white Anthranilic acid is an aromatic acid with the formula C6H4NH2CO2H. 2021-03-27 · In hydrocarbon: Aromatic hydrocarbons …All compounds that contain a benzene ring possess special stability and are classified as benzenoid aromatic compounds. Certain other compounds lack a benzene ring yet satisfy the criterion of special stability and are classified as nonbenzenoid aromatic compounds. The ring and the three double bonds fit the molecular formula, but the structure doesn't explain the chemical behavior of benzene at all well. Each of the double bonds would be expected to show the characteristic behavior of an alkene and undergo addition reactions, but this is not how benzene reacts.

Benzene forms a ring as follows. In one version, cited by Carl Jung in ''The Psychology of Transference,'' Kekule discovered the benzene ring after dreaming of ''the Royal Marriage,'' the image of a dancing king and queen used by The chemical formula of benzene is C6H6, so it has six carbon (C) atoms and six hydrogen (H) atoms.
