R-3.4 FUNCTIONAL REPLACEMENT

Characteristic (Functional) Groups

R-3.4 Functional Replacement

The replacement of oxygen atoms or hydroxy groups by other atoms or groups can be described by prefixes attached to, or by infixes inserted into, names of characteristic groups, functional parent compounds or trivial names. For example, "thio" indicates replacement of oxygen by sulfur in the suffixes "-thiosulfonic acid" and "-carbothioic acid", and in the functional parent name "phosphorothioic acid". Similarly, "peroxo" or "peroxy" indicates replacement of an oxygen atom by the

group in the suffix "-peroxycarboxylic acid", in the functional parent name "phosphoroperoxoic acid", and in the trivial name "peroxyacetic acid". A list of prefixes and/or infixes is gives in Table 8.
