maleic acid and fumaric acid which is more acidic

- Quora. In maleic acid in contrast the carboxyle groups are fixid in proximity, which favours chemical interactions. The reason for the acidity of maleic acid is that the two -COOH groups interfere with each other in the unionized molecule because the double bonds force all the atoms (except the hydrogens in … Therefore, since the first H+ in maleic acid is much easier to dissociate, maleic acid is more acidic than fumaric acid.

Why maleic acid is more acidic than fumaric acid? Still have questions? Maleic Acid - Assignment Point. fumaric having higher melting point, indicates that it is a trans isomer and it is more stable compare to maleic acid (since it requires higher energy to break more stable compounds). Media Coverage | Dear The maleate monoanion shows intramolecular H-bonding, whereas fumarate monoanion shows intermolecular H-bonding. Both maleic and fumaric acids are diacids where two carboxylic acid groups are present. You have joined No matter what your level. Sitemap | Both properties of maleic acid can be explained on account of the intramolecular hydrogen bonding that takes place in maleic acid at the expense of intermolecular interactions, and that are not possible in fumaric acid for geometric reasons. the presence of another acid just act as a catalyst to make the reaction go forward, from maleic to fumaric.
