Answer #1

2. Yes, there are total 6 non-aromatic/non-alkene protons.

2 protons at 1.79 ppm which corresponds to e and 4 protons which corresponds to d

3. Yes, there are two peaks upfield of 70 ppm seen in 13C NMR spectrum at 22.9 ppm and 28.4 ppm indicating the aliphatic carbons e & d respectively. Peak at 77 ppm is a solvent peak of CDCl3.

4. Peak for carbonyl group seen far downfield at 190.3ppm.

    The IR/spectrum shows the value, 1st photo shows the instructions. Attached are 2 sets of spectra. Each set is worth 25 points. Not all sets have a Mass Spectrum, but do have information that was obtained from MS and some sets do not have a "C-NMR and don't really need one. Look at each spectrum individually and clearly list and comment on the structural Characteristics you can determine from that spectrum. (Chemical shifts, splitting patterns, coupling constants, fragmentation patterns, absorption...
