C+H+O compounds

Each hydrogen added to a molecule can be considered as a proton plus a one-electron reduction of the redox state, while each oxygen counts as a two-electron oxidation. Thus a net addition of H₂O is a simple hydration with no net change in redox state and frequently occurs reversibly in aqueous solution. These relationships may be viewed in the following table (peroxides and radicals are excluded; unstable or hypothetical compounds are italicized).

	O0	O1	O2	O3	O4
H4	methane	methanol	methanediol	orthoformic acid	orthocarbonic acid
H3	methyl radical	methoxy radical
H2	methylene	formaldehyde	formic acid	carbonic acid
H0		carbon monoxide	carbon dioxide	carbon trioxide
