Nomenclature of alkanes

The nomenclature of non-cyclic alkanes Definition Non-cyclic alkanes are carbon and hydrogen compounds without cycles or multiple bonds. The structure of a name Prefixes-Root-ane The root The root is formed by the main chain which is the longest chain of C atoms. 1 atome C:   ....meth.... 2 atomes C:  ....eth.... 3 atomes C:  ....prop.... 4 atomes C:  ....but.... 5 atomes C:  ....pent.... 6 atomes C:  ....hex.... 7 atomes C:  ....hept.... 8 atomes C:  ....oct.... 9 atomes C:  ....non.... 10 atomes C: ....dec.... Prefixes The side chains are prefixed. Their nomenclature is the same as for the main root, except the suffix - yl . The numbering of their attachment position to the main chain is done in such a way that the number formed by the ranked indices in ascending order is as small as possible.
