Chemical compound
Ethylene dione or ethylenedione, also called dicarbon dioxide, Carbon peroxide, ethenedione, or ethene-1,2-dione, is a chemical compound with the formula C2O2 or O=C=C=O. It is an oxide of carbon (an oxocarbon), and can be described as the carbon-carbon covalent dimer of carbon monoxide.[1] It can also be thought of as the dehydrated form of glyoxylic acid (H(C=O)COOH), or a ketone of ethenone H2C=C=O.
