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 (C9H12O): A = C9H12O IR of Compound A (C9H12O): A= 7.0-7.4 ppm a = 5 H, multiplet B= C= 1.0-1.2 ppm e = 3 H, doublet 2.6-2.8 ppm d=2 H, CrO3 H₂SO4 doublet 1500 1000 Si 2 11 10 HSP-00-078 5.0 ppm b=1 H, broad singlet 8 7 5 3 PPM ¹H NMR of Compound B (C9H100): 7.0-7.4 ppm a = 5 H, 9 8 multiplet 7 4.0-4.2 ppm c=1 H, sextet 6 5 ppm 3.6 ppm b = 2H, 4 singlet 3 2.2 ppm c = 3H, 2 singlet 1 B = C9H100 0 4800 A= B= C= 3604 64 9352 81 3087 72 3063 64 3040 72 3029 72 3006 68 ↑↑ BC 3000 A 3339 14 1476 42 1434 87 2977 34 1948 81 1874 84 1647 84 1504 62 1584 79 1497 20 3109 55 3086 47 3064 43 3028 30 3004 00 2944 27 27 1497 1155 74 1110 79 1082 49 7 1046 D * 900 81 856 70 767 60 748 17 699 4 602 TO an 596 62 1376 60 1800 24 1272 74 1243 74 1178 10 573 57 826 81 496 63 IR of Compound B (C₂H100): LOD ↑↑ A B 3000 4000 2967 77 2925 70 2857 84 LG 4 LEIS B 1588 21 1683 41 200€ 1646 81 1492 81 1450 25 1430 62 1380 13 1315 52 63 1303 2000 1267 6 1161 58 1150 74 1103 79 1079 62 1025 50 1001 74 EVENUE C VEMBER 966 37 923 72 751 15 731 79 821 14 515 51 689 17 1000
