IUPAC Nomenclature -Review Many aliphatic acids have historical names. IUPAC names:drop the -e from the parent alkane and add the suffix -oic acid if the compound contains a carbon-carbon double bond,change the infix -an-to -en- COOH COOH COOH CeHs Propenoic acid trans-2-Butenoic acid trans-3-Phenyl- (Acrylic acid) (Crotonic acid) propenoic acid (Cinnamic acid)
