Dibenzodioxin
Encyclopedia
Dibenzo-p-dioxin or dibenzo-1,4-dioxin is an organic heterocyclic
compound in which two benzene rings are connected by a 1,4-dioxin ring. Its molecular formula is C12H8O2. The two oxygen atoms occupy opposite (para) positions in a six-membered dioxin ring.
The isomer
ic compound dibenzo-o-dioxin or dibenzo-1,2-dioxin has two adjacent oxygen atoms (ortho).
As no detailed information is available on the dibenzo-ortho-dioxin isomer, it is expected to be highly unstable, with peroxide
-like characteristics.
The general name dibenzodioxin usually refers to dibenzo-p-dioxin.
Dibenzodioxin forms the scaffold for the class of chemicals known collectively as dioxins
, which include the potent toxins polychlorinated dibenzodioxins (PCDDs) such as 2,3,7,8-tetrachlorodibenzodioxin

Isomer
In chemistry, isomers are compounds with the same molecular formula but different structural formulas. Isomers do not necessarily share similar properties, unless they also have the same functional groups. There are many different classes of isomers, like stereoisomers, enantiomers, geometrical...
