NMR problem
All isomers of the molecular formula C3HsBr3 are shown below. On each compound draw all hydrogen atoms and label unique hydrogen's with an A. B, etc. Indicate the multiplet you would expect to see for each unique hydrogen. Assume that all coupling constants between unique pairs of hydrogen's are different. You may use the abbreviations given in Table 8.5. Part of Compound A is assigned to get you started. The H NMR spectra of two of the compounds shown in 6A are provided below. Match the spectrum to the compound by drawing the structure of the compound on the spectrum. Assign each resonance.
