WitrynaMaleic acid. HO2CCH=CHCO2H. Synonyms: cis -Butenedioic acid, Toxilic acid. CAS null. Molecular Weight 116.07. Browse Maleic acid and related products at … WitrynaTrans isomers are usually more stable than cis isomers because there is no steric interaction, or repulsion, between the carboxyl groups of the molecule. The more negative heat of formation value of trans alkenes also show that these compounds are more stable than cis alkenes.
