Question

Consider a Chemical reaction between Sulfolene and Maleic Anhydride in Xylene:

1. (2 pts) Identify the diene and dienophile in the above reaction
2. (1 pt) Using IR spectral studies, how do you identify if the desired Diel’s alder adduct is formed in the above reaction?
3. (2 pts) Calculate the percentage yield, if 1g of product is formed when 2.0 g of 3-sulfolene, 1.2 g of finely powdered maleic anhydride, and 1.0 mL of xylenes are used in the above reaction.
4. (1 pt) What is the purpose of using CaCl₂ trap in the above reaction?
5. (2 pts) Can we use one of the following solvents instead of Xylene? Explain
   1. Hexane
   2. Water
6. (2 pts) In which container do you dispose toluene and Xylene mixture after filtering the desired product.
   1. Aqueous waster      b. Flammable waste   
   2. c. Down the sink   d. NO need to dispose. It will evaporate on it’s own.

Answer 1

Here the dinophile= maleic-n-hydride; and diene=Sulfolene

No we cant use water or hexane as solvent rather than Xylene.

after the reaction, there is no need to dispose the solution, it will evaporate on its own
