Identify the compound A (C5H10O) with the proton NMR spectrum
shown. Compound A has IR absorptions at 3200–3600 cm–1 (strong,
broad), 1676 cm–1 (weak), and 965 cm–1, and also has 13C NMR
absorptions (attached protons in parentheses) at δ 17.5 (3), δ 23.3
(3), δ 68.8 (1), δ 125.5 (1), and δ 135.5 (1). Compound A may be
resolved into enantiomers; draw one molecule of A, omitting
wedge/dash bonds.

In H2O, the 31P NMR spectrum of the compound gives 2 lines
shifted from each other by about 1ppm, corresponding to the hydrate
and ketone in the ratio of 60:40.
You want to measure the rates of interconversion between them in
the range of 0.1-3.0 per second using a cross relaxation method.
Both the hydrate and ketone have T1's of 5.0 second and linewidths,
delta v1/2 of 2 hz. The experiments are performed in a field such
