Statement-1 : of fumaric acid is more than maleic acid.
Statement-2 : Conjugate base of fumaric acid is stabilised by intramolecular H-bonding.
Options:
Answer:
C
Solution:
Statement-1 is True: Fumaric acid (trans-isomer) is less acidic than maleic acid (cis-isomer) in its first dissociation, so its value is higher.
Statement-2 is False: The conjugate base of maleic acid (not fumaric acid) is stabilized by intramolecular hydrogen bonding because its carboxyl groups are on the same side. In contrast, the carboxyl groups in fumaric acid are far apart (trans configuration), preventing any intramolecular hydrogen bonding in its conjugate base.
Therefore, Statement-1 is correct and Statement-2 is incorrect, making (C) the right choice.
