Treatment of alcohol A (molecular formula C5H12O) with CrO3, H2SO4, and H2O affords B with molecular formula C5H10O, which gives an IR absorption at 1718 cm−1. The 1H NMR spectrum of B contains the following signals: 1.10 (doublet, 6 H), 2.14 (singlet, 3 H), and 2.58 (septet, 1 H) ppm. What are the structures of A and B?
The 'H NMR spectrum of compound A (C3H100) has four signals: a multiplet at 8 = 7.25-7.32 ppm (5 H), a singlet at d = 5.17 ppm (1 H), a quartet at d = 4.98 ppm (1 H), and a doublet at ô = 1.49 ppm (3 H). There are 6 signals in its 13C NMR spectrum. The IR spectrum has a broad absorption in the -3200 cm-1 region. Compound A reacts with KMNO4 in a basic solution followed by acidification to give compound B with the molecular formula C7H6O2. Draw structures for compounds A and B.

Please show work 1. Compound A has molecular formula C5H10O. It shows three signals in the 1H-NMR spectrum - a doublet of integral 6 at 1.1 ppm, a singlet of integral 3 at 2.14 ppm, and a quintet of integral 1 at 2.58 ppm. Suggest a structure for A and explain your reasoning.
(3) These natural compounds will have different numbers of 1H-NMR signals in different NMR solvents like CDC13 and methanol-d4. How many signals do you anticipate for each compound respectively in CDC13 and methanol-d4? LOCH 3 OHC. vanillin OH LOH acetoaminophen HO thymol
[References] The mass spectrum of compound A shows the molecular lon at m/z 85, an M + 1 peak at m/z 86 of approximately 6% abundance relative to M, and an M + 2 peak at m/z 87 of less than 0.1% abundance relative to M. Assuming that compound A has only C, H, and one N atoms, determine the molecular formula, and then draw a possible. structure if compound A has an IR absorption at 1620-1680 cm 1, 2 absorptions at 3280-3450 cm¹, and a (q, 1H) absorption at 4.6-5.7 8 in the ¹H-NMR spectrum.
