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.
