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 ...
The term carbonyl can also refer to carbon monoxide as a ligand in an inorganic or organometallic complex (a metal carbonyl, e.g. nickel carbonyl). The remainder of this article concerns itself with the organic chemistry definition of carbonyl, such that carbon and oxygen share a double bond.
Double bonds occur most commonly between two carbon atoms, for example in alkenes. Many double bonds exist between two different elements: for example, in a carbonyl group between a carbon atom and an oxygen atom. Other common double bonds are found in azo compounds (N=N), imines (C=N), and sulfoxides (S=O). In a skeletal formula, a double bond ...
In chemistry, the double bond rule states that elements with a principal quantum number (n) ... Carbon monoxide (C≡O) silynes: phosphaalkynes: Carbon monosulfide (C ...
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 bonding in carbon dioxide is often described as consisting of two C=O double bonds, although in such delocalized systems, bond order is less distinct. As mentioned above, carbon forms triple bonds to oxygen in carbon monoxide and its derivatives, which includes acylium ions and metal carbonyls.
In carbon monoxide, − C≡O +, the bond order between carbon and oxygen is 3. In thiazyl trifluoride N≡SF 3, the bond order between sulfur and nitrogen is 3, and between sulfur and fluorine is 1. In diatomic oxygen O=O the bond order is 2 (double bond). In ethylene H 2 C=CH 2 the bond order between the two carbon atoms is also 2.
The distance between the two bridging carbon is 1.37 Å, which is in the range of a carbon-carbon double bond; in addition, the Ta-C-C' bond angle is 173°, further confirming the π bonding of the Ta-C-C'-Ta' system. The main pathway of the mechanism of this reaction is illustrated below without the solvent adducts:
