Carbon compounds. Carbon compounds are defined as chemical substances containing carbon. [ 1][ 2] More compounds of carbon exist than any other chemical element except for hydrogen. Organic carbon compounds are far more numerous than inorganic carbon compounds. In general bonds of carbon with other elements are covalent bonds.
Carbon is one of the few elements that can form long chains of its own atoms, a property called catenation.This coupled with the strength of the carbon–carbon bond gives rise to an enormous number of molecular forms, many of which are important structural elements of life, so carbon compounds have their own field of study: organic chemistry.
Carbon-carbon bonds are strong and stable. Through catenation, carbon forms a countless number of compounds. A tally of unique compounds shows that more contain carbon than do not. [89] A similar claim can be made for hydrogen because most organic compounds contain hydrogen chemically bonded to carbon or another common element like oxygen or ...
In non-polar covalent bonds, the electronegativity difference between the bonded atoms is small, typically 0 to 0.3. Bonds within most organic compounds are described as covalent. The figure shows methane (CH 4), in which each hydrogen forms a covalent bond with the carbon. See sigma bonds and pi bonds for LCAO descriptions of such bonding. [22]
Some chemical authorities define an organic compound as a chemical compound that contains a carbon–hydrogen or carbon–carbon bond; others consider an organic compound to be any chemical compound that contains carbon. For example, carbon-containing compounds such as alkanes (e.g. methane CH4) and its derivatives are universally considered ...
Carbon–hydrogen bond. In chemistry, the carbon-hydrogen bond ( C−H bond) is a chemical bond between carbon and hydrogen atoms that can be found in many organic compounds. [ 1] This bond is a covalent, single bond, meaning that carbon shares its outer valence electrons with up to four hydrogens. This completes both of their outer shells ...
Carbon is a key element to all known life. It is in all organic compounds, for example, DNA, steroids, and proteins. [6] Carbon's importance to life is primarily due to its ability to form numerous bonds with other elements. [17] There are 16 kilograms of carbon in a typical 70-kilogram human. [18] Silicon-based life's feasibility is commonly ...
Carbones are a class of molecules containing a carbon atom in the 1 D excited state with a formal oxidation state of zero where all four valence electrons exist as unbonded lone pairs. [1] These carbon-based compounds are of the formula CL 2 where L is a strongly σ -donating ligand, typically a phosphine (carbodiphosphoranes) or a N ...
