PLEASE ANSWER THIS QUESTION!!!!
The NMR spectrum of 3-nitroaniline was taken in deuterated dimethylsulfoxide (DMSO), not CDCl3. Why? a) The residual CHCl3 peak would get in the way of the aromatic peaks in the product.b) 3-Nitroaniline is not soluble in CDCl3.c) DMSO allows visualization of the peaks for the NH2 group.d) 3-Nitrobenzamide is not soluble in CDCl3.
HO OMe Vanillin 4-hydroxy-3-methoxybenzaldehyde HO OMe OH Vanillyl Alcohol 4-hydroxy-3-methoxybenzyl alcohol 7. If you had to use ¹H NMR to verify that you actually synthesized vanillyl alcohol from vanillin, describe at least two key differences in the ¹H NMR spectra of these two compounds that would support your claim. 22
Can I get this question answered with an explanation Why is it better to acquire the 1H-NMR spectrum in DMSO-d6 and not in CDCl3?
B. Draw the structure of the synthesized product (do not include side or by products) from the experiments performed. How can IR spectroscopy be used to monitor the progress of each of the following reactions (if reaction went to completion and/or check the purity of the final product)? What absorptions would be observed in the IR spectrum? And if IR spectroscopy could not have been used, briefly explain why.
Part 3B Set 2. Can 1H NMR spectroscopy be used to differentiate between the two compounds? Briefly explain why or why not. Predict the 1H NMR spectrum for each compound (include integration, multiplicity, and approximate chemical shift). Either draw the actual spectrum or put in a data table format.

Interpret the NMR results in terms of purity. What should a chemist do to improve the yield or purity of the product? Discuss the key parts of the NMR for the starting material and pure product. Focus on the peaks that show up after 3 ppm. For the starting material, discuss what those 2 peaks (around 3.5 ppm and 4.7 ppm) correspond to in the structure of cyclohexanol. For the pure product, discuss why those 2 peaks are missing, and there is a new peak for 2H at around 5.6 ppm. Then, discuss the NMR for your actual product from the reaction. Does it contain pure product? If not, what else is there? How do you know this based on the NMR? Based on your understanding of the reaction and LeChatelier’s principle, how can you improve the reaction yield? How can you better purify the reaction product?
