i anu ToVI pea ev of impünties? Pass the product in to your instructor. Questions for experiment 7 1. Consider the 'H NMR spectrum of a pure sample of the Diel-Alder product. Match the signal pairs with the proton pairs listed on the numbered structure. Base your answer on chemical shifts for the signals expected from theory (consult the lecture textbook, Chapter 13). CH3 Hs H6 COOH H7 Proto signals at δ 5.9 and 5.6 signals at δ 4.5 and 4.2 signals at δ 2.8 and 1.2 A) Protons Hio and Hip B) Protons for CHs and Hs C) Protons H and H 2. What is the expected splitting pattem for the CHs protons? Choose one of the following: singlet, doublet, triplet, quartet, or doublet of doublets. 3. An exo transition state in the Diels-Alder reaction would have given the following initial Diels-Alder product
