MALEIC ACID VS FUMARIC ACID

MALEIC ACID VS FUMARIC ACID‪@unlockchemistry‬ #UNLOCKCHEMISTRY #PARVESHNARANG Maleic acid is the cis isomer of butenedioic acid, whereas fumaric acid is the trans isomer. ... Maleic acid is soluble in water whereas fumaric acid is not and the melting point of maleic acid (130 - 131 degree centigrade) is also much lower than that of fumaric acid (287 degree centigrade).Both properties of maleic acid can be explained on account of the intramolecular hydrogen bonding that takes place at the expense of intermolecular interactions. Maleic acid is converted into maleic anhydride by dehydration, to malic acid by hydration, and to succinic acid by hydrogenation. It reacts with thionyl chloride or phosphorus pentachloride to give the maleic acid chloride (it is not possible to isolate the mono acid chloride). Maleic acid is a reactant in many Diels-Alder reactions. FAQ Why is maleic acid more acidic than fumaric? Is maleic acid strong or weak? What type of stereoisomers are maleic and fumaric acid? What is geometrical isomerism discuss it for maleic and fumaric acids? What is the pKa of maleic acid?
