need help figuring the unknown and starting these questions. Identify the important (diagnostic) peaks from the IR spectrum. corresponds to each peak below. Be sure to also add labels your IR spectrum (write the corresponding bond type next to each peak on the IR spectrum itself) 2. List the cm 1 and the bond that 3. List all possible classes of compounds that your unknown could be (i.e. could the unknown be a ketone, alcohol, ester, carboxylic acid? does the...
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...
