Compound C has molecular formula C9H10O. The mass spectrum shows a parent ion (M+) peak at 134 and a base peak (largest peak) at 105 atomic mass units. The IR spectrum shows major signals at 3029, 2925, 2721, 1708, 1495, 1452, 1375, 1152, 745, and 699 cm-1. The 1H-NMR spectrum shows signals at 2.35 (singlet, 3H), 3.65 (doublet, 2H), 7.11 (doublet 2H), 7.18 (doublet, 2H), and 9.73 (triplet, 1H) ppm. The 13C-NMR spectrum shows signals at 21.1, 50.2, 128.7, 129.5, 129.7, 137.1, and 199.6 ppm. Suggest a structure for C and explain your reasoning.
