Write the reaction of benzocaine with aqueous hydrochloric acid (i.e. H3O+; the Cl– is irrelevant). Abbreviate benzocaine as Ar–NH2, where Ar represents a generalized "aryl" group (in this case a phenyl with a –CO2Et group). The pKa of the conjugate acid of benzocaine is 2.5. Based on pKa values, does this acid-base equilibrium favor reactants or products?
