Please use what you know about 'H NMR (# of Peaks, Chemical Shift, Integration of peaks, and splitting to come up with and justify a reasonable structure for the following molecule. Note: The molecules will have the chemical formula as stated. C8H100. ?H-NMR Integration (from more shielded to less shielded) - 3H,2H,2H, 3H
10. (8 points) For each of the following molecules predict the "C and 'H NMR spectra. For the "C NMR predict the number of peaks and the shift. For the 'H NMR you will need to predict the shift, multiplicity, and integration of the peaks. CH3 HC не ең, H₃C =O % b-CH3 11. (6 points) Propose a structure for a compound with the chemical formula C.H.Cl, that fits the following 1H NMR data 2.18 8 (3H, singlet) 4.16 8...
predict the 1H NMR Spectra with the molecule. include the
integration, chemical shift and splitting pattern
H. H₃ C' chemical formula : ciotoo
For each peak of the NMR, describe the chemical shift,
functional group, integration, splitting pattern, neighbors, the
molecule that the peak represents, and finally draw the final
structure of the NMR.

CHIM 245 Spectroscopy Problem Set #2 In this problem set there are two unknown compounds. You are provided with the formula, IR spectrum, "C NMR spectrum, and 'H NMR spectrum for each compound. Each unknown is worth 10 points, with an...
Draw the expected H NMR spectrum for each molecule. Pay
attention to the chemical shift and splitting. Mark the integration
of each peak. Then assign each peak in the NMR to hydrogen atoms in
the structure.
