Specific Classes of Compounds

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

R-5.7.2.1 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-5.7.2.1

(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-5.7.2.2 Selenium acids containing selenium directly linked to an organic group are named in the same way as the corresponding sulfur acids (see R-5.7.2.1) by replacing the stem "sulf-" with "selen-" in the name.

Example to R-5.7.2.2
