Question

Fill out the table according to the images right above it.

1) To assist your analysis of the spectral data of the product mixture, predict the 'H-NMR spectrum of each of the possible mono-nitrated bromobenzenes shown in the table below. Calculate the chemical shift (ppm) using empirical (Curphy-Morrison) parameters, and include the coupling pattern and approximate J value (Hz) of each of the non-equivalent 'H- atoms. Use the 'H-atom labeling key provided on page 11-9.
