The pK a ?s of five p-substituted benzoic acids (YC 6 H 4 CO 2 H) follow.
Question:
The pKa?s of five p-substituted benzoic acids (YC6H4CO2H) follow. Rank the corresponding substituted benzenes (YC6H5) in order of their increasing reactivity toward electrophilic aromatic substitution. If benzoic acid has PKa = 4.19, which of the sub-stituents are activators and which arc deactivators?
