WebSolution. Maleic and Fumaric are dibasic acids. Maleic acid is stronger than fumaric acid in its first ionisation, because maleate ion is stabilised by intramolecular hydrogen bonding sinch both COOH group is in cis position. In fumaric acid there is no intramolecular hydrogen bonding because both the COOH group present in trans position so ... WebThe polar covalent bond is much stronger in strength than the dipole-dipole interaction. The former is termed an intramolecular attraction while the latter is termed an intermolecular …
WebFumaric acid is trans-butenedioic acid and Maleic acid is cis-butenedioic acid. Maleic acid exhibits the intramolecular hydrogen bonding that is not possible in fumaric acid for geometric reasons. these intramolecular hydrogen bonds make it difficult to release hydrogen to act as an acid.

Maleic acid has a heat of combustion of -1,355 kJ/mol., 22.7 kJ/mol higher than that of fumaric acid. Maleic acid is more soluble in water than fumaric acid. The melting point of maleic acid (135 °C) is also much lower than that of fumaric acid (287 °C). 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 rea…
