Quinone - Wikipedia The quinones are a class of organic compounds that are formally "derived from aromatic compounds [such as benzene or naphthalene] by conversion of an even number of –CH= groups into –C(=O)– groups with any necessary rearrangement of double bonds", resulting in "a fully conjugated cyclic dione structure"
Quinone | Definition Uses | Britannica Quinones occur as biological pigments (biochromes), for example, including the benzoquinones, naphthoquinones, anthraquinones, and polycyclic quinones The quinones are found in bacteria, in certain fungi, and in various higher plant forms, but in only a few animals
26. 2: Quinones - Chemistry LibreTexts Quinones are not aromatic compounds but are conjugated cyclic diketones However, quinones and the related aromatic arenols are readily interconverted, and their chemistry is largely interdependent …
