    INTRODUCTION Maleic acid and Fumaric acid are both compounds belonging to the carboxylic acids class. In this experiment‚ we formed the two isomers of 1‚2-ethylenedicarboxylic acid and tested the solubility and melting points of both of these products. Both of these compounds involve a carbon-carbon double bond that is composed of one σ bond and one π bond. The overlap of sp2 hybrid orbitals forms the σ bond‚ and one empty p orbital forms the π bond. This process is illustrated in the figure below:
