What is 3.3 CHM622 NMR about?

1) 1H-NMR spectroscopy shows benzene ring hydrogens between 7-8 ppm due to shielding by ring currents. Substituents can shield or deshield nearby hydrogens. 2) Alkyl-substituted benzene rings have equivalent ring hydrogens. Substituents with unshared pairs separate hydrogens into two groups. Carbonyl groups deshield ortho and para hydrogens. 3) Para-disubstituted benzene rings show a pair of doublets that merge as the substituents become more similar, ultimately giving a single peak for identical substit
