An unlabeled flask contains a compound with a molecule mass of 86. The ¹H NMR data are$\delta$ 2.10 (pentet, J = 7.1, 2H), 2.30 (t, J = 7.1, 2H), and 4.30 (t, J = 7.1, 2H). The ¹³C NMR data are $\delta$ 22.5, 27.9, 68.8, and 178.1. The compound gives a positive hydroxamate test. Deduce the structure of the unknown compound.
