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.
For example, carbon-containing compounds such as alkanes (e.g. methane CH 4) and its derivatives are universally considered organic, but many others are sometimes considered inorganic, such as halides of carbon without carbon-hydrogen and carbon-carbon bonds (e.g. carbon tetrachloride CCl 4), and certain compounds of carbon with nitrogen and ...
Carbon-based life. The Lewis structure of a carbon atom, showing its four valence electrons. Carbon is a primary component of all known life on Earth, and represents approximately 45–50% of all dry biomass. [ 1] Carbon compounds occur naturally in great abundance on Earth.
Carbon (from Latin carbo 'coal') is a chemical element; it has symbol C and atomic number 6. It is nonmetallic and tetravalent —meaning that its atoms are able to form up to four covalent bonds due to its valence shell exhibiting 4 electrons. It belongs to group 14 of the periodic table. [ 16]
Numerous organic compounds have other common names, often originating in historical source material thereof. The systematic IUPAC name is not always the preferred IUPAC name , for example, lactic acid is a common, and also the preferred, name for what systematic rules call 2-hydroxypropanoic acid.
Isoflavones (phytoestrogens) use the 3-phenylchromen-4-one skeleton (with no hydroxyl group substitution on carbon at position 2).

List of straight-chain alkanes. The following is a list of straight-chain alkanes, the total number of isomers of each (including branched chains), and their common names, sorted by number of carbon atoms. [ 1][ 2] Number of C atoms. Number of isomers [ 3][ 4]
