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.
Carbon-based compounds form the basis of all known life on Earth, and the carbon-nitrogen-oxygen cycle provides a small portion of the energy produced by the Sun, and most of the energy in larger stars (e.g. Sirius). Although it forms an extraordinary variety of compounds, most forms of carbon are comparatively unreactive under normal conditions.
Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. [1]
Carbon dioxide. Other organic carbonyls are urea and the carbamates, the derivatives of acyl chlorides, chloroformates and phosgene, carbonate esters, thioesters, lactones, lactams, hydroxamates, and isocyanates. Examples of inorganic carbonyl compounds are carbon dioxide and carbonyl sulfide. [citation needed]
This would still exclude urea. Moreover, this definition still leads to somewhat arbitrary divisions in sets of carbon-halogen compounds. For example, CF 4 and CCl 4 would be considered by this rule to be "inorganic", whereas CHF 3, CHCl 3, and C 2 Cl 6 would be organic, though these compounds share many physical and chemical properties ...
Carbon is most commonly used in its amorphous form. In this form, carbon is used for steelmaking, as carbon black, as a filling in tires, in respirators, and as activated charcoal. Carbon is also used in the form of graphite, for example as the lead in pencils. Diamond, another form of carbon, is commonly used in jewelry. [18]
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 ...
A homologue (also spelled as homolog) is a compound belonging to a homologous series. [1] Compounds within a homologous series typically have a fixed set of functional groups that gives them similar chemical and physical properties. (For example, the series of primary straight-chained alcohols has a hydroxyl at the end of the carbon chain ...
