(a) Assign protons to the peaks in the NMR spectrum of 4,4-dimethylcyclohex-2-en-1-one in Figure 13-30(a). Explain the splitting that gives the triplets at and (b) Assign protons to the peaks in the NMR spectrum of in Figure 13-30(b). Explain the splitting seen in the three multiplets at and . Explain how you know which of these multiplets corresponds to which methylene groups in the molecule.
