Homework Answers
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.

Experimental Data Only report the IR absorptions that provide diagnosis for the major functional groups. Copies of your spectra will be included in your lab report with this information written on the spectra. However, the information should also be included in the body of the report in a text format similar to the example given below IR cm1: 1735 (C-o); MS:...

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...

and mechanism
FTIR and NMR Spectra After completing a reaction and working up the products, it is still necessary to confirm that the correct product was formed. The most common tools used for this analysis are Fourier Transform Infrared (FTIR) and Nuclear Magnetic Resonance (NMR) spectroscopy. In the virtual laboratory, 'H and C NMR spectra are available. Details on interpreting FTIR and NMR spectra are found in your textbook. Your instructor may or may not...

85% yield), please interpret/discuss HNMR/IR in as much detail as
possible and assign peaks on HNMR (which peak represents which
protons of which group, etc). Note: I already know how you
determine the formation of the product so you can skip that part of
part b).
