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
Ethers (R−O−R) consist of an oxygen atom between the two attached carbon chains. The shorter of the two chains becomes the first part of the name with the -ane suffix changed to -oxy, and the longer alkane chain becomes the suffix of the name of the ether. Thus, CH 3 OCH 3 is methoxymethane, and CH 3 OCH 2 CH 3 is methoxyethane (not ...
Unbranched, saturated hydrocarbon chains are named systematically with a Greek numerical prefix denoting the number of carbons and the suffix "-ane". [ 5 ] In 1866, August Wilhelm von Hofmann suggested systematizing nomenclature by using the whole sequence of vowels a, e, i, o and u to create suffixes -ane, -ene, -ine (or -yne), -one, -une, for ...
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 another molecule. They are formed by adding the suffix "-yl" to the hydrocarbon prefix.
While the use of the affix mono-is rarely necessary in organic chemistry, it is often essential in inorganic chemistry to avoid ambiguity: carbon oxide could refer to either carbon monoxide or carbon dioxide. In forming compound affixes, the numeral one is represented by the term hen-except when it forms part of the number eleven (undeca-): hence
The type of subunit, be it a heterocycle, a heteroatom chain, a carbocycle, or a carbon chain, determines the colour arrow to follow. [9] Using the shortest path in order of decreasing precedence of subunits, the correct order of the subunits is determined using Figure 1. In the example, the oxy subunits in the CRUs are heteroatom chains.
The prefixes for naming carbon chains containing one to four carbons. For chains containing five or more carbons, the inorganic prefixes (e.g. pent = 5, hept = 7) are ...
The prefix n describes a straight-chain carbon skeleton without branches, whereas iso describes a branched skeleton, without specifying any further details. More generally, iso is a compound which is isomeric to the n compound (a compound in which individual atoms or atomic groups are rearranged)
