If one of the methyl groups attached to the third carbon atom were instead an ethyl group, then the name would be 3-ethyl-2,3-dimethylpentane. When there are different alkyl groups, they are listed in alphabetical order. In addition, each position on an alkyl chain can be described according to how many other carbon atoms are attached to it.
If there are different groups, they are added in alphabetical order, separated by commas or hyphens. The longest possible main alkane chain is used; therefore 3-ethyl-4-methylhexane instead of 2,3-diethylpentane, even though these describe equivalent structures.
Alkyl groups are saturated hydrocarbons substituents with the general formula C n H 2n+1 Pages in category "Alkyl groups" The following 7 pages are in this category ...
Alkyl compounds are chemical compounds formally derived from alkanes by replacement of one hydrogen atom with other atoms or functional groups. Alkyl compounds contain alkyl groups , C n H 2 n +1 , and have the general formula C n H 2 n +1 X, where X is any chemical element or group.
Traditionally the names of the alkyl groups were written in order of increasing complexity, for example methyl ethyl ketone. However, according to the rules of IUPAC nomenclature, the alkyl groups are written alphabetically, for example ethyl methyl ketone. When the two alkyl groups are the same, the prefix "di-" is added before the name of ...
