Extra Credits (5 points) Propose a possible structure for a compound with molecular formula C-H12O2 that shows absorption at 1720 cm-' and no absorption in the range of 1500 - 1700 cm' or 2600 - 2800 cm in its IR spectrum and only three signals in its 'H NMR spectrum.
Compound (C5H8O) has a strong IR absorption band at 1745 cm-1. The
broad-band proton decoupled 13C spectrum of this compound shows
three signals: at ?220 (C), 23 (CH2), and 38 (CH2). Propose a
structure for this compound.
5-14) A compound A has a strong, broad IR absorption at
3200–3500 cm–1 and the proton NMR spectrum shown below. Treatment
of compound A with H2SO4 gives compound B, which has the NMR
spectrum shown at bottom and a molecular ion at m/z = 84 in its EI
mass spectrum. Identify compounds A and B.
