Specific Classes of Compounds

R-5.7.2 Chalcogen acids containing chalcogen atoms directly linked to an organic group

R- Sulfur acids containing sulfur atoms directly linked to an organic group are named substitutively on the basis of a parent hydride name by adding an appropriate suffix as illustrated in Table 14. The prefixes "sulfo-" and "sulfino-" are used to express sulfonic and sulfinic acid groups as substituents, respectively.

Examples to R-

(not Toluene-2,4-disulfonic acid,

see R-9.1 Table 19(a)

Some trivial names are allowed (see R-9.1, Table 30)

R- Selenium acids containing selenium directly linked to an organic group are named in the same way as the corresponding sulfur acids (see R- by replacing the stem "sulf-" with "selen-" in the name.

Example to R-

R-5.7.3 Phosphorus and arsenic acids containing phosphorus or arsenic atoms derictly linked to an organic group
R-5.7.4 Salts and esters
R-5.7.5 Lactones, lactams, lactims, and analogues
R-5.7.6 Acid halides
R-5.7.7 Anhydrides and their analogues
R-5.7.8 Amides, imides, and hydrazides
R-5.7.9 Nitriles, isocyanides and related compounds
