Substituted naphthalene nomenclature

Web2004-09-16. Naphthalene-2,6-dicarboxylic acid is a dicarboxylic acid. It derives from a hydride of a naphthalene. ChEBI. 2,6-dicarboxynaphthalene is a solid. This compound belongs to the naphthalenecarboxylic acids. These are compounds containing a napthalene moiety with a ring carbon which bears a carboxylic acid group. WebNaphthalene is more reactive than benzene, both in substitution and addition reactions, and these reactions tend to proceed in a manner that maintains one intact benzene ring. The following diagram shows three oxidation and reduction reactions that illustrate this feature.
