General acid/base catalysis takes advantage of solutes more acidic than water (pKa < 14) and more basic that water (conjugate acid pKa’s of greater than 0) to protonate and deprotonate atom groups that are ill-prepared to carry additional charge along a reaction pathway. Returning to Figure G.1, th ...
