3. Complete the table below by assigning the peak groups in the 1H-NMR spectrum to the labeled protons in the structure below. Where possible, report the coupling constants (J) in Hz. Splitting patterns: s=singlet, d=doublet, t=triplet, dd=doublet of doublets, dt=doublet of triplets, ddd=doublet of doublet of doublets m=multiplet.
