Consider the following Proton and Carbon NMR spectra for the same compound, and it contains Chlorine. Decide on a structure which is consistent with the spectral data, and 'assign" both spectra as best as you can. "Assign" = draw structure, label (a,b,c etc) and indicate which peaks belong to which type.
