In this experiment the objective was to perform a Diels-Alder reaction using cyclopentadiene and maleic anhydride to synthesize the product‚ cis-Norbornene-5‚6-endo-dicarboxylic anhydride. The Diels-Alder reaction is one of the most important reactions in organic chemistry and was first investigated by Otto Diels and Kurt Alder in Germany. It is a [4+2] concerted cycloaddition reaction which involves a diene and a dienophile. The Diel-Alder reaction are mainly used for creating new carbon-carbon
