Carbon monoxide (chemical formula CO) is a poisonous, flammable gas that is colorless, odorless, tasteless, and slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond. It is the simplest carbon oxide. In coordination complexes, the carbon monoxide ligand is called carbonyl. It is ...
In carbon monoxide (CO, isoelectronic with dinitrogen) the oxygen 2s orbital is much lower in energy than the carbon 2s orbital and therefore the degree of mixing is low. The electron configuration 1σ 2 1σ* 2 2σ 2 2σ* 2 1π 4 3σ 2 is identical to that of nitrogen.
For organic chemistry, a carbonyl group is a functional group with the formula C=O, composed of a carbon atom double-bonded to an oxygen atom, and it is divalent at the C atom. It is common to several classes of organic compounds (such as aldehydes , ketones and carboxylic acids ), as part of many larger functional groups.
A model of the carbon monoxide molecule. A monoxide is any oxide containing only one atom of oxygen. A well known monoxide is carbon monoxide; see carbon monoxide poisoning. The prefix mono (Greek for "one") is used in chemical nomenclature. [1] In proper nomenclature, the prefix is not always used in compounds with one oxygen atom. [2]
In chemistry, an oxocarbon or oxide of carbon is a chemical compound consisting only of carbon and oxygen. [1] [2] The simplest and most common oxocarbons are carbon monoxide (CO) and carbon dioxide (CO 2).
Iron pentacarbonyl is a homoleptic metal carbonyl, where carbon monoxide is the only ligand complexed with a metal. Other examples include octahedral Cr(CO) 6 and tetrahedral Ni(CO) 4 . Most metal carbonyls have 18 valence electrons , and Fe(CO) 5 fits this pattern with 8 valence electrons on Fe and five pairs of electrons provided by the CO ...

Examples of molecular oxides are carbon dioxide and carbon monoxide. All simple oxides of nitrogen are molecular, e.g., NO, N 2 O, NO 2 and N 2 O 4 . Phosphorus pentoxide is a more complex molecular oxide with a deceptive name, the real formula being P 4 O 10 .
