a.) Your TA will give you a 1H NMR spectrum of the 3
nitro-aniline product. Using your NMR knowledge and the special NMR
section in the lab book, as sign the 4 peaks in the spectrum to
each of the protons in the product.
b.) Explain your assignment, specifically how you differentiated
between Ha and Hb.
Please answer both parts thanks!

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...

This is the H NMR spectrum for the product of a reaction between either benzaldehyde, 4-methybenzaldehyde, 4-methoxybenzaldehyde, or cinnamaldehyde with either acetone, cyclopentanone, cyclohexanone, 4-methylcyclohexanone. Assign the peaks in the 1H NMR spectrum to this product. Hand-draw the 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 acceptable to assign multiple groups of protons to a series of overlapping...

Assign the peaks in your spectrum by:
(1) drawing what you think the structure of the product is directly
on your spectrum; (2) identifying the protons with code letters
(e.g., “Ha”, “Hb”, “Hc”, etc.), but grouping protons that give rise
to the same signal under the same label; (3) writing “Ha”, “Hb”,
“Hc”, etc., near the appropriate peaks so that the assignment is
clear; (4) identifying impurity peaks.
