CH2CHO
CH2CHO is a small, carbon-centered radical with the chemical formula C2H3O. It is commonly described as a formylmethyl radical, consisting of a formyl group (CHO) bonded to a methylene unit (CH2) and bearing an unpaired electron, typically localized on the methylene carbon (CH2•–CHO).
The radical arises in gas-phase reactions involving acetaldehyde (CH3CHO) and related hydrocarbons, via hydrogen abstraction by
In chemical kinetics, CH2CHO participates in oxidation and chain-propagating steps, including reactions with molecular oxygen to
CH2CHO has been detected and characterized in laboratory experiments using spectroscopic techniques that probe its rotational
