Sample pre-lab quiz for Diels-Alder Reaction experiment.

 

1) The Diels Alder reaction is facilitated by:

  1. an electron donating group on the diene
  2. an electron withdrawing group on the dienophile
  3. both a and b
  4. none of the above

2) Of the following reagents used in the Diels Alder lab, which requires the most careful handling, because it is toxic, flammable, and has a noxious odor?

  1. maleic anhydride
  2. hexanes
  3. dicyclopentadiene
  4. ethyl acetate

3) How many peaks do you expect from a 1H-NMR of the Diels Alder product you will synthesize (below)?

  • 3
  • 6
  • 8
  • 24

    4) Indicate a potential problem (i.e., why won't it work well) for the following Diels-Alder reaction:

    1. the Diels Alder reaction is facilitated by the presence of electron withdrawing components on the dienophile
    2. the Diels Alder reaction is facilitated by the presence of electron donating component on the diene
    3. diene needs to be in the S-cis conformation
    4. diene needs to be in the S-cis conformation

    5) Under reversible conditions, will the exo- or the endo- Diels-Alder product form?

    1. exo
    2. endo

    6) What diene and dienophile produced the following Diels-Alder adduct?

    1. I have no clue, show me!
    2. I know the answer, but show me anyway!

    7) Provide the products for the following Diels-Alder reactions. Be sure to indicate the stereochemistry of the products where applicable.
