Question

An aqueous solution of propanone (acetone, 1) of total volume 0.120 mL was analysed by quantitative 1H NMR, using the CH protons of (E)-butenedioic acid (fumaric acid, 2) to provide an internal standard. A stock solution of 2 with concentration = 10.00 x 10-3 mol L-1 was prepared by dissolving pure solid 2 in deuterium oxide (D2O). The solution of 1 was mixed with a 0.400 mL aliquot of the stock solution of 2 and the 400 MHz 1H NMR spectrum of the mixture was recorded (see Table 2 below).
