Iso Neo Sec Tert Là Gì

     
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 size a continuous, unbranched (linear) chain. If a functional group (such as an alcohol) is present that functional group is on the end of the chain. Not lớn be confused with "nor", which indicates a missing methyl group.

The prefix "sec
" or "s" is used when the functional group is bonded to 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 or more carbons.
