H,CO A в H. D Proton NMR: 7.1 (doublet, 2H), 6.9 (doublet, 2H), 4.0 (quartet, 2H), 3.5 (singlet, 2H), 2.2 (singlet, 3H), 1.3 (triplet, 3H) Carbon-13 NMR: 205, 157, 130, 126, 114, 65, 49, 30, 15 IR (below): Note that none of the choices has an O-H group, so the peak at 3500 must be for water impurity? LOD TRANSMETTANCEI
