Date : September 11, 2011 TITLE: Diels-Alder Reaction PURPOSE: In this Lab, I will perform Diels- Alder reaction between cyclopentadiene and maleic anhydride. I will also analyze the final product via infrared spectroscopy and melting point analysis. CHEMICAL REACTIONS: Diels- Alder reaction is a concerted reaction in which no intermediate is formed. The reaction occurs between a diene with 4π electrons and a dienophile with 2π electrons. Having a s-cis conformation for the diene can allow for proper orbital overlap. Also, electron donating groups can increase the reactivity of diene. However, electron withdrawing groups can increase the reactivity of dieneophile. PHYSICAL PROPERTIES: NOTES AND OBSERVATIONS: Weight of Maleic Anhydride= 0.2 g Weight of ethyl acetate= 1 ml After adding maleic anhydride to ethyl acetate , the maleic anhydride dissolved completely. 0.2 ml of cyclopentadiene was added to solution, the tube started getting warm
