In chemical nomenclature, the IUPAC nomenclature of organic chemistry is a method of naming organic chemical compounds as recommended [1] [2] by the International Union of Pure and Applied Chemistry (IUPAC). It is published in the Nomenclature of Organic Chemistry (informally called the Blue Book). [3]
Norbornane (also called bicyclo[2.2.1]heptane). Unsubstituted cycloalkanes that contain a single ring in their molecular structure are typically named by adding the prefix "cyclo" to the name of the corresponding linear alkane with the same number of carbon atoms in its chain as the cycloalkane has in its ring.
CH 4 + O 2 → 2 H 2 O + C. See the alkane heat of formation table for detailed data. 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 ...
The Geneva Nomenclature of 1892 was created as a result of many other meetings in the past, the first of which was established in 1860 by August Kekulé. Another entity called the International Association of Chemical Societies (IACS) existed, and on 1911, gave vital propositions the new one should address: [ 2 ]
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
Alkyl cycloalkanes are chemical compounds with an alkyl group with a single ring of carbons to which hydrogens are attached according to the formula C n H 2n . They are named analogously to their normal alkane counterpart of the same carbon count: methylcyclopropane , methylcyclobutane , methylcyclopentane , methylcyclohexane , etc. [ 1 ]
Polycyclic alkanes include cubane, basketane, and tetrahedrane. Spiro compounds have two or more rings that are connected through only one carbon atom. The mode of ring-closing in the formation of many alicyclic compounds can be predicted by Baldwin's rules .
[1] [2] Retained names are often used for the most fundamental parts of a nomenclature system: almost all the chemical elements have retained names rather than being named systematically, as do the first four alkanes, benzene and most simple heterocyclic compounds. Water and ammonia are other examples of retained names.
