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
For example, the simplest alkane is CH 4 methane, and the nine-carbon alkane CH 3 (CH 2) 7 CH 3 is named nonane. The names of the first four alkanes were derived from methanol, ether, propionic acid and butyric acid, respectively.
The standard enthalpy change of combustion, Δ c H ⊖, for alkanes increases by about 650 kJ/mol per CH 2 group. Branched-chain alkanes have lower values of Δ c H ⊖ than straight-chain alkanes of the same number of carbon atoms, and so can be seen to be somewhat more stable.
Pentane is an organic compound with the formula C 5 H 12 —that is, an alkane with five carbon atoms. The term may refer to any of three structural isomers, or to a mixture of them: in the IUPAC nomenclature, however, pentane means exclusively the n-pentane isomer, in which case pentanes refers to a mixture of them; the other two are called isopentane (methylbutane) and neopentane ...
Alkanes as substituents are called alkyl groups Subcategories. This category has the following 5 subcategories, out of 5 total. B. Butane (2 C, 11 P) E. Ethane (1 C ...
Hydrocarbon prefixes: These prefixes indicate the number of carbon atoms in a straight-chain alkane. Some examples include: meth- (1 carbon) eth- (2 carbons) prop- (3 carbons) but- (4 carbons) pent- (5 carbons) hex- (6 carbons) Alkyl group prefixes: These prefixes are used to name alkyl groups (chains of carbon atoms) that are attached to ...
In traditional names various qualifiers are used to label isomers, for example, isopropanol (IUPAC name: propan-2-ol) is an isomer of n-propanol (propan-1-ol). The term moiety has some overlap with the term "functional group". However, a moiety is an entire "half" of a molecule, which can be not only a single functional group, but also a larger ...
Neopentane, also called 2,2-dimethylpropane, is a double-branched-chain alkane with five carbon atoms. Neopentane is a flammable gas at room temperature and pressure which can condense into a highly volatile liquid on a cold day, in an ice bath, or when compressed to a higher pressure.
