An unknown substance has the formula C6H12O2. The compound shows four singlets in the 1H NMR spectrum at 3.8 (1 H, s), 2.6 (2 H, s), 2.2 (3 H, s) and 1.3 (6 H, s) ppm, respectively. . The 3.8 ppm proton exchanges with deuterium upon addition of D2O. In the IR spectrum, a wide absorption in the range of 3600-3200 cm-1 and a more sharp absorption at 1703 cm-1 is seen, among other things. Write down the structure of the substance based on this information.
