Prefixes functional class nomenclature

Ethers are named m substitutive lUPAC nomenclature as alkoxy derivatives of alkanes Functional class lUPAC names of ethers are derived by listing the two alkyl groups m the general structure ROR m alphabetical order as separate words and then adding the word ether at the end When both alkyl groups are the same the prefix di precedes the name of the alkyl group... 

In order of decreasing priority for citation of a functional class name, and the prefix for substitutive nomenclature, are the following related compounds ... 

Radicofunctional Nomenclature. The procedures of radicofunctional nomenclature are identical with those of substitutive nomenclature except that suffixes are never used. Instead, the functional class name (Table 1.9) of the compound is expressed as one word and the remainder of the molecule as another that precedes the class name. When the functional class name refers to a characteristic group that is bivalent, the two radicals attached to it are each named, and when different, they are written as separate words arranged in alphabetical order. When a compound contains more than one kind of group listed in Table 1.9, that kind is cited as the functional group or class name that occurs higher in the table, all others being expressed as prefixes. 

Representing crosslinked polymers is more complicated. There is the same difficulty in nomenclature for crosslinked polymers. As a result, standard denominations were introduced for this class of polymers. After the prefix poly , there is the name of the functional group that bonds the repetition units (polyaldehyde, polyamide, polycarbonate, polyester, polysulfide, polyphosphonitrile, etc.) (Rudin, 1999). 

Given this fundamental system of using a prefix to give the number of carbons and a suffix to describe the class of molecules (and/or functional group), a set of rules allows virtually any organic molecule to be named. This nomenclature system uses the so-called the lUPAC selection rules ...
