1,4-Benzoquinone, commonly known as para-quinone, is a chemical compound with the formula C 6 H 4 O 2. In a pure state, it forms bright-yellow crystals with a characteristic irritating odor, resembling that of chlorine, bleach, and hot plastic or formaldehyde. This six-membered ring compound is the oxidized derivative of 1,4-hydroquinone. [4]
Benzoquinone (C 6 H 4 O 2) is a quinone with a single benzene ring. There are 2 (out of 3 hypothetical) benzoquinones: 1,4-Benzoquinone, most commonly, right image (also para-benzoquinone, p-benzoquinone, para-quinone, or just quinone) 1,2-Benzoquinone, less commonly, left image (also ortho-benzoquinone, o-benzoquinone, ortho-quinone)
Relative to benzoquinone, more strongly oxidizing quinones include chloranil and 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (also known as DDQ). [6] The oxidizing power of quinones is enhanced by the presence of acids. [7] In acidic conditions, quinone undergoes two-electron and two-proton reduction to hydroquinone.

Duroquinone is an organic oxidant (C 6 (CH 3) 4 O 2). It is related to 1,4-benzoquinone by replacement of four H centres with methyl (Me) groups. The C 10 O 2 core of this molecule is planar with two pairs of C=O and C=C bonds. [1] The compound is produced via nitration of durene (1,2,4,5-tetramethylbenzene) followed reduction to the diamine ...
2,5-Dihydroxy-1,4-benzoquinone or 2,5-dihydroxy-para-benzoquinone is an organic compound with formula C 6 H 4 O 4, formally derived from 1,4-benzoquinone by replacing two hydrogen atoms with hydroxyl (OH) groups. It is one of seven dihydroxybenzoquinone isomers. It is a yellow solid [1] with planar molecules [2] that exhibits ferroelectric ...
