Chapter 13.8D, Problem 13.9P

1. a. Assign protons to the peaks in the NMR spectrum of 4,4-dimethylcyclohex-2-en-1-one in Figure13-30(a). Explain the splitting that gives the triplets at δ 1.8 and δ 2.4.
2. b. Assign protons to the peaks in the NMR spectrum of β - ionone in Figure13-30(b). Explain the splitting seen in the three multiplets at δ 1.5, δ 1.65, and δ 2.1. Explain how you know which of these multiplets corresponds to which methylene groups in the molecule.
