Preferred Label : replacement name;
IUPAC definition : p A name in which the replacement of an atom or a group of a parent structure by
another atom or group is indicated by affixes attached to or inserted into the name
of the parent structure. There are two main types of replacement names. /p ol
li Skeletal replacement name. A name in which the replacement of skeletal atoms and
their associated hydrogen atoms is indicated by non-detachable prefixes. When carbon
atoms are replaced by heteroatoms this method has been called 'a' nomenclature since
the prefixes end in 'a'. Certain names in which the prefix 'thio-', 'seleno-' or 'telluro-'
indicates replacement of a skeletal oxygen atom by a sulfur, selenium or tellurium
atom, respectively, are also skeletal replacement names. /li li Functional replacement
name. A name containing prefixes or infixes which indicate the replacement of an oxygen
atom or hydroxy group of a characteristic group, functional parent or class name by
other atoms or groups. /li /ol ;
