Order of Precedence of Functional Groups
In organic chemistry, functional groups are specific groups of atoms within molecules that are responsible for the
characteristic chemical reactions of those molecules. The same functional group will undergo the same or similar
chemical reaction(s) regardless of the size of the molecule it is a part of.When compounds contain more than one functional group, the order of precedence determines which groups are
named with prefix - i.e. as substituents -, or suffix forms - i.e. as part of the parent name of the molecule. The
highest precedence group takes the suffix, with all others taking the prefix form. However, double and triple bonds
only take suffix form (-ene and -yne) and are used with other suffixes.Prefixed substituents are ordered alphabetically (excluding any modi fiers such as di-, tri -, et c.), e.g.
chlorofluoromethane, not fluorochloromethane. If there are multiple functional groups of the same type, either
prefixed or suffixed, the position numbers are ordered numerically (thus ethane-1,2-diol, not ethane-2,1-diol.)
