They are named by replacing the final “e” of the corresponding alkane by “oic acid”. <> Several examples are shown below. •Generally in IUPAC system of naming the final “ –e” of the alkane is replaced by “ amide”. 1 0 obj %���� <> Given the structure of a carboxylic acid, carboxylate ion, ester, amide, or amine molecule, be able to give the systematic names and vice versa.
