I NH 3) Critical analysis (5 points): (a) Your TA will give you a 'H NMR spectrum of the 3-nitroaniline product. Using your NMR knowledge and the special NMR section in the lab book (especially pages 48 ON and 49), assign the 4 peaks in the spectrum to each of the protons in the product- you will need to use coupling pattern and chemical shift to complete the assignment. W (b) Explain your assignment, specifically how you differentiated between HA...

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...

1. In the H NMR, draw the structure of the molecule directly on
the spectrum and identify each unique proton. Indicate which proton
is responsible for each peak.
2. In the IR spectrum, indicate which functional group is
responsible for each important peak. Attempt to identify at least
five important peaks. In you discussion, indicate which peaks are
most helpful in determining whether or not you converted the
starting material to the desired product.
3. Compare the IR spectrum of...
