In organic chemistry, the carbon number of a compound is the number of carbon atoms in each molecule. [1] The properties of hydrocarbons can be correlated with the carbon number, although the carbon number alone does not give an indication of the saturation of the organic compound. When describing a particular molecule, the "carbon number" is ...
The numbers for that type of side chain will be grouped in ascending order and written before the name of the side-chain. If there are two side-chains with the same alpha carbon, the number will be written twice. Example: 2,2,3-trimethyl- . If there are both double bonds and triple bonds, "en" (double bond) is written before "yne" (triple bond).
The α-carbon (alpha-carbon) refers to the first carbon atom that attaches to a functional group, such as a carbonyl. The second carbon atom is called the β-carbon ( beta -carbon), the third is the γ-carbon ( gamma -carbon), and the naming system continues in alphabetical order.
IUPAC nomenclature is used for the naming of chemical compounds, based on their chemical composition and their structure. [1] For example, one can deduce that 1-chloropropane has a Chlorine atom on the first carbon in the 3-carbon propane chain.
Number of C atoms Number of isomers [3] [4] Number of isomers including stereoisomers [3] [5] Molecular Formula Name of straight chain Synonyms 1 1 1 CH 4: methane: methyl hydride; natural gas 2 1 1 C 2 H 6: ethane: dimethyl; ethyl hydride; methyl methane 3 1 1 C 3 H 8: propane: dimethyl methane; propyl hydride 4 2 2 C 4 H 10: n-butane: butyl ...
The double bond of an alpha olefin is between the #1 and #2 (IUPAC) or α and β (common) carbon atoms. In organic chemistry, terminal alkenes (alpha-olefins, α-olefins, or 1-alkenes) are a family of organic compounds which are alkenes (also known as olefins) with a chemical formula C x H 2x, distinguished by having a double bond at the ...
Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structuressssss, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. [1]
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 CH 4) and its derivatives are universally considered ...
