Part 5: Putting It All TogetherWe don't quite have all the parts of an NMR analysis yet, but we can go a long way to solving the structure of a moleculejust by considering the number, chemical shifts, and in the case of 1H NMR, the integrals of the signals. In the nextpages, a compilation of 'H and 13C NMR spectra are shown for all but one of the organic compounds shown below. Yourjob is to match the compound with the spectra. Don't just write the structure, some justification for your choices must begiven as well.`NO2HONO2

2. The specific gravities (S.G.) of a number of radio-active components have been determined. The masses of the components have been found accurately, by weighing them, but their geometry is complex and the volumes have been found by using the water- displacement method. 18-7 18-3 18-4 18.9 18-8 18.6 19-2 18.9 19-8 18-8 17:0 19-5 19.3 (a) Give details of the likely concerns associated with this process.

Set up a standard curve, excluding outliers (experimental and statistical) and determine the protein concentration in the unknown sample in mg/ml (up to 3 decimal places).
Mass spectrometry X-ray diffraction Both techniques Answer Bank protein may be denatured small amounts of protein are sufficient can detect a covalent modification to a protein requires a large amount of protein analysis requires information about the protein-coding gene or genes protein sample must be pure protein must be conformationally stable Mass Spectrometry and x-ray diffraction are common biochemical techniques for characterizing proteins. Classify each statement based on whether it applies to MS, X-Ray, or both.
