Nomenclature and Properties of Carboxylic Acids

In the lUPAC systematic nomenclature, the final e of the parent alkane is dropped, the suffix oic is added, and the separate word acid is added. Diacids are named similarly, except that the suffix is dioic, and the final e is not dropped. Cyclic acids are named as cycloalkanecarboxylic acids. Tahle 17.1 shows some common mono-and diacids along with some of their physical properties and common names, many of which are stfil used.
