251 pset-ch 14 Identify compounds A-E from the information given. Please show your work in order to receive full credit: Compounds A and B both had molecular formulas of C,H2. Their proton NMR spectra showed signals exclusively between 0.5-1.5ppm, and their BCNMR spectra showed signals between 0-35ppm. Compound A NMR spectrum, however, consisted of only three signals, while compound B's consisted of four Compound C had a molecular formula of CHio. Like compounds A and B, the NMR signals were all exclusively in the 0.5-1.5ppm and 0-35ppm ranges for proton and carbon, respectively. However, for compound C, each of these spectra consisted of only a single peak. Free-radical bromination of C produced only a single product. Free-radical bromination of compound A produced a mixture of products, including compound D. Compoun D's proton NMR spectrum is the first spectrum shown below. Like compound A's spectrum, compound D's CNMR conisted of only three signals, although one was further downfield than in the original. However, consisted of five signals. Free-radical bromination of compound B produced a single product, compound E. Compound E's proton NM is the second spectrum shown below. Like the original spectrum of compound B, compound E's "CNMRs consisted of four signals, although one was further downfield than in the original. L6H 10 9 8 7 6 54 3 2 10
