(a) by adding a prefix "hydro-" to the parent name (Rule C-32),
(b) by adding a functional class name after the parent name (Rule C-33).
For the nomenclature of addition compounds, see Rule D-1.55.
1.52 - The prefix "hydro-" is used as described in Rules A-23.1, B-1.1, B-1.2, C-16 and C-32.1 as denoting the addition of one hydrogen atom. Multiplying prefixes are used as needed.
1.53 - Bonding numbers higher than those listed in Rule D-1.61 may be indicated by hydro prefixes; however, the designation given by Rule D-1.62 is preferred.
Example to Rule D-1.52
1.54 - Important functional class names involved in additive nomenclature are:
Examples to Rule D-1.53
|Class name||Added atom or group|
1.55 - The names of addition compounds are formed by citing those of the individual compounds, separated by a rule (long hyphen). Boron compounds and water are always cited last and in that order. Other molecules are cited in order of increasing number; any which occur in equal numbers are cited in alphabetical order. The numbers of each individual molecule are indicated by Arabic numerals separated by a solidus, the total expression being enclosed in parentheses.
Examples to Rule D-1.54
Examples to Rule D-1.55
Aluminium chloride - ethanol (1/4)
Methanol - boron trifluoride (2/1)
