  2. Carbon compounds - Wikipedia

    en.wikipedia.org/wiki/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.

  3. Carbon - Wikipedia

    en.wikipedia.org/wiki/Carbon

    Carbon's abundance, its unique diversity of organic compounds, and its unusual ability to form polymers at the temperatures commonly encountered on Earth, enables this element to serve as a common element of all known life. It is the second most abundant element in the human body by mass (about 18.5%) after oxygen. [17]

  4. Organic chemistry - Wikipedia

    en.wikipedia.org/wiki/Organic_chemistry

    Organometallic chemistry is the study of compounds containing carbon–metal bonds. Organic compounds form the basis of all earthly life and constitute the majority of known chemicals. The bonding patterns of carbon, with its valence of four—formal single, double, and triple bonds, plus structures with delocalized electrons—make the

  5. Organic compound - Wikipedia

    en.wikipedia.org/wiki/Organic_compound

    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 ...

  6. Carbon-based life - Wikipedia

    en.wikipedia.org/wiki/Carbon-based_life

    The branch of chemistry that studies organic compounds is known as organic chemistry. [15] Carbon is the 15th most abundant element in the Earth's crust, and the fourth most abundant element in the universe by mass, after hydrogen, helium, and oxygen. Carbon's widespread abundance, its ability to form stable bonds with numerous other elements ...

  7. Carbon–carbon bond - Wikipedia

    en.wikipedia.org/wiki/Carboncarbon_bond

    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 carboncarbon 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.

  8. Carbones - Wikipedia

    en.wikipedia.org/wiki/Carbones

    The structure of carbodicarbenes greatly resembles that of carbodiphosphoranes. [4] Computational data for a N-methyl-substituted carbodicarbene predicted a carbon-carbon bond with a length only marginally longer than a C=C bond in a typical allene at 1.358 Å (compared with 1.308 Å for allene), but with a significantly bent bond angle of 131.8° (compared to 180° for a standard linear ...

  9. Chemistry - Wikipedia

    en.wikipedia.org/wiki/Chemistry

    Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
