3. Due to time constraints, the preparation of 1-iodo-4-nitrobenzene was no longer included in today's experiment. However, if it was, you would have used IR to confirm you synthesized 1-iodo-4- nitrobenzene from p-nitroaniline. How can IR spectroscopy differentiate these two compounds?

In order to determine (or to confirm the 13C NMR analysis of) the regioselectivity of the addition, determine the number of signals that would appear in each region of the spectrum for the carvone starting material and the two regioisomeric products. For instance, each product has two methyl carbons, so you should write "2" in each cell in the last row of the table. Circle the regioisomeric product that has numbers of each category of proton that match those observed in the NMR spectrum of carvone epoxide. CH3 CH3 CH3 Н. H H. H H. CH3 CH3 CH3 H.

One student, when conducting this experiment, overlooked instruction #4 in Part B that stated "Repeat steps 2 and 3 above two more times with fresh 2-mL portions of sodium bicarbonate solution." Upon conducting TLC analysis, this student found that the final isolated biphenyl was contaminated with some 2-chlorobenzoic acid. Explain, on a specific. molecular level, how and why this student's error in part B led to a poor separation. Be
