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.

IR & 13C NMR Unknown Your mission is to determine the structure of your unknown from the nula, IR and C NMR spectra. Assign all of your C NMR absorptions. You want know which resonances correspond to which parts of the product's structure. The best way to do this is to draw a picture of the molecule right on the NMR spectrum then label each C on the molecule with a letter (C. Ch. Cc...)....

Draw the expected H NMR spectrum for each molecule. Pay
attention to the chemical shift and splitting. Mark the integration
of each peak. Then assign each peak in the NMR to hydrogen atoms in
the structure.
