a) (2 pts) For the IR spectrum illustrated below, identify and label major peaks with the appropriate functional group.
b)_(3 pts) For the 1H-NMR spectrum given below, label each peak with the appropriate proton(s). 9 1H 00 1H 2H 02 5 PPM 2H L 6H 3H
c) (2 pts) For the 13C-NMR spectrum illustrated below, label each peak with the carbon atom(s). 180 160 140 120 100 PPM 80 60 40 20 0
d) First, propose three reasonable structures that match the spectra. Second, provide a detailed structure elucidation and draw the structure of the compound represented by molecular formula and spectra given. Show your analysis. Draw possible structures (3 pts, 1 pt each). Circle the final answer (1 pt)
