20. A compound with the formula C5H100 exhibits the following C NMR signals Broadband decoupled: 207, 45, 28, 16, and 12 ppm DEPT-90: no signals DEPT-135: positive signals at 28 and 12 ppm, negative signals at 45 and 16 ppm.
Determine the correct structure of the compound, which shows following 13C NMR DEPT-135 data is 13C NMR DEPT-135: negative peaks at δ30.2, 31.9, 61.8, 114.7 ppm; positive peak at 130.4 ppm
Based on these graphs of 13CNMR and 1HNMR what would the final
structure of the molecule look like? The molecular weight is 98.
