5 pts] Raw integration values are never the nice round numbers you are typically given in lab, and are often imprecise because of subtle differences in the way that the spins of different nuclei 1. interact with the magnetic field. Raw integration values are given in red below. One common strategy for confirming the presence of protic hydrogen atoms is to add D20, which will replace moderately acidic hydrogens (up to about pKa 18) with NMR-silent D atoms. Determine the structures corresponding to each of the spectra below, and assign each peak in each spectrum. 11238 CHi6O 7473 1275 disappears after D O shake 8 7 6 5 4 3 1 chemical shift, ppm (8) а) ЗН 6.3 Hz Нz 6.3 Hz 6.2-! Нz 6.3 На ЗН 2H 1H disappears on D O shake 8 7 5 4 3 1 0 chemical shift, ppm (8) (This compound has a formula of CsH100, and has IR absorptions at 3200 3600 (strong, broad) and 1676 cm (weak), and 5 different 13C NMR signals. It is optically active and can be resolved into enantiomers.)
