Draw the structures in the bolded boxes below each IR from the given spectra and reaction information. Identify major IR peaks (see arrows). Label the referenced hydrogens from the 1H NMR on the structure you draw using the lowercase letters given for the peaks on the 1H NMR. 1H NMR of Compound A (C8H10O): A = C8H10O IR of Compound A (C8H10O): 7.0-7.4 ppm a = 5 H, multiplet 2.6-2.9 ppm c = 2 H, triplet 3.6-3.9 ppm b = 2 H, triplet 2.0 ppm d = 1 H, broad singlet PCC 1H NMR of Compound B (C8H8O): B = C8H8O IR of Compound B (C8H8O): 7.0-7.45 ppm b = 5 H, multiplet 9.75-9.8 ppm a = 1 H, triplet 2.7-2.8 ppm c = 2 H, doublet
