Using the data below, select the correct structure corresponding to the NMR below. Peak splitting abbreviations are given in the spectrum. 'm' stands for multiplet (peak splitting is complex), 'sx' stands for sextet-6 peaks, 'p' stands for pentet- 5 peaks Molecular formula: C9H1602 Integration values: 0.98 ppm (1.5), 1.3 ppm (1), 1.44 ppm (1), 2.19 ppm (1), 2.9 ppm (1), 3.68 ppm (1.5), 5.55 ppm (0.5), 5.7 ppm (0.5) d 9 m m SX P 5 5 3 PPM O OS O O O= NMR below.
