In the NMR spectrum of benzoic acid we look for a singlet peak
at 12.70 delta due to the presence of the carboxylic acid
proton.

The attached 1H NMR spectrum of
3-chlorobenzoic acid, recorded as a solution in CDCl3 +
D2O, lacks the broad resonance due to the carboxylic
acid proton. Explain the lack of the indicated resonance in this
spectrum.
