1. Quinone

   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". The archetypical member of the class is 1,4-benzoquinone or cyclohexadienedione, often called simply "quinone" (thus the name of the class). Other important examples are 1,2-benzoquinone (ortho-quinone), 1,4-naphthoquinone and 9,10-anthraquinone. The name is derived from that of quinic acid (with the suffix "-one" indicating a ketone), since it is one of the compounds obtained upon oxidation of quinic acid. Quinic acid, like quinine is obtained from cinchona bark, called quinaquina in the indigenous languages of Peruvian tribes.

1. quinone

   Quinone is a type of organic compound characterized by having two carbonyl groups (C=O) connected by a conjugated system in a six-membered unsaturated ring. Quinones are oxidized derivatives of aromatic compounds such as phenol and are often used as oxidizing agents or pigments. They occur widely in nature and play key roles in various biological functions such as photosynthesis and respiration.

1. Quinone

   A quinone is 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– groups with any necessary rearrangement of double bonds," resulting in "a fully conjugated cyclic dione structure." The class includes some heterocyclic compounds. The prototypical member of the class are 1,4-benzoquinone or cyclohexadienedione, often called simply quinone. Other important examples are 1,2-benzoquinone, 1,4-naphthoquinone and 9,10-anthraquinone. Quinones are oxidized derivatives of aromatic compounds and are often readily made from reactive aromatic compounds with electron-donating substituents such as phenols and catechols, which increase the nucleophilicity of the ring and contributes to the large redox potential needed to break aromaticity.. Quinones are electrophilic Michael acceptors stabilised by conjugation. Depending on the quinone and the site of reduction, reduction can either rearomatise the compound or break the conjugation. Conjugate addition nearly always breaks the conjugation.
