2. In Experiment 4B, it was shown from the NMR spectrum that the meta-di-substituted Nitration product had
been recorded as a major product:
COOME
COOME
HNO3
H,SO,
NO2
Major product
However, there were two other possible but less favorable routes, i.e. ortho- or para- positions for the nitronium
to attack the aromatic ring with. Draw the H-NMR spectrum for Methyl p-Nitrobenzoate in case the
substitution takes place at the para-position. Pay attention to the chemical shift, the splitting pattern, and
approximate the integration in your spectra.
