Answer #1

Here you go:

6. The most probable peaks that are assigned to the protons in the structure is listed below:

H1: 10.38 ppm; H2: 6.76 ppm; H3: 7.54 ppm; H4: 2.40 ppm; H5: 2.40 ppm; H6: 2.40 ppm; H7: 6.23 ppm; H8: 6.62 ppm.

According to HOMEWORKLIB RULES, I can't answer the rest of the questions.

5) Assign the peaks in the 'H NMR spectrum of your product. Draw your structure on the NMR spectrum and label each set of inequivalent protons. Use these labels in assigning the peaks. In some cases the aromatic peaks may overlap, so it is OK to assign groups of protons to a series of overlapping peaks if necessary. Try to be as specific as possible in your assignment, though. Discuss in detail how the NMR spectrum is only consistent with...

Provide the correct structure for your unknown based on the spectroscopic data provided. Provide the correct name for your compound. Either the IUPAC name, or a commonly accepted name (i.e., ethyl acetate in place of ethyl ethanoate) will be accepted.IR spectrum: Assign as many peaks as possible. In particular, you should assign peaks that were important in making your structural interpretation (i.e. functional group peaks such as OH, C=O, N-H, etc.). 1H-NMR spectrum: Assign all the peaks in the spectrum...

Label the significant peaks in the IR and NMR spectra. When analyzing the signals in the 'HNMR, be sure to include all appropriate information. For example: 3H, singlet, 0 neighbors, and c (the letter referring to the corresponding unique type of hydrogens that were labeled in the structure). It is recommended to provide more analysis for each signal than what is described above, when necessary, such as labeling any coupling constants if any are provided For NMR label each peak...
