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 ...
MO diagram of dihydrogen Bond breaking in MO diagram. The smallest molecule, hydrogen gas exists as dihydrogen (H-H) with a single covalent bond between two hydrogen atoms. As each hydrogen atom has a single 1s atomic orbital for its electron, the bond forms by overlap of these two atomic orbitals. In the figure the two atomic orbitals are ...
A carbon–oxygen bond is a polar covalent bond between atoms of carbon and oxygen. [ 1 ] [ 2 ] [ 3 ] : 16–22 Carbon–oxygen bonds are found in many inorganic compounds such as carbon oxides and oxohalides , carbonates and metal carbonyls , [ 4 ] and in organic compounds such as alcohols , ethers , and carbonyl compounds .
Otherwise, if a diatomic molecule consists of two different atoms, such as carbon monoxide (CO) or nitric oxide (NO), the molecule is said to be heteronuclear. The bond in a homonuclear diatomic molecule is non-polar. A periodic table showing the elements that exist as homonuclear diatomic molecules under typical laboratory conditions.
The term inert gas is context-dependent because several of the inert gases, including nitrogen and carbon dioxide, can be made to react under certain conditions. [1] [2] Purified argon gas is the most commonly used inert gas due to its high natural abundance (78.3% N 2, 1% Ar in air) [3] and low relative cost.
Make sure to install extra carbon monoxide detectors 5 to 20 feet from sources of CO gas, including the stove, dryer, or furnace, and follow the manufacturer's guidelines for specific ...

The C–O vibration, typically denoted ν CO, occurs at 2143 cm −1 for carbon monoxide gas. The energies of the ν CO band for the metal carbonyls correlates with the strength of the carbon–oxygen bond, and inversely correlated with the strength of the π-backbonding between the metal and the carbon.
