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). 4H PPM 4H ㅇ
c)_(2 pts) For the 13C-NMR spectrum illustrated below, label each peak with the carbon atom(s). 60 50 40 PPM 30 20 10
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)
