Common name: A nomenclature system useful for naming simple organic molecules. It often fails for more complex molecules, in which case systematic or (better yet) IUPAC nomenclature is preferable.
The prefix "n-" (or
normal) is used when all carbons form a continuous, unbranched (linear) chain. If a functional group (such as an alcohol) is present that functional group is on the kết thúc of the chain. Not khổng lồ be confused with "nor", which indicates a missing methyl group.

The prefix "sec" or "
s" is used when the functional group is bonded to lớn a secondary carbon. This prefix is only useful for a four-carbon chain. It is not applicable with a shorter chain, & it is often ambiguous when the chain has five sầu or more carbons.
