Protons in acid-base reactions

Basic Idea Obviously, the protons in acid-base reactions are simply transferred from one base B to another B ... 

What unifies the various definitions of an equivalent is that, in each case, one equivalent supplies or accepts 1 mole of unit charges—in the form of protons (in acid-base reactions), or electrons (in oxidation-reduction reactions), or the ions themselves (in ion combinations). Because electric charge is strictly conserved, the number of moles of charge supplied by one reactant must equal the number of moles of charge accepted by the other reactant. Thus, the system of equivalence is merely a convenient but arbitrary scheme for rebalancing equations such that 1 eq of one substance reacts exactly with 1 eq of another substance to produce 1 eq of each product. For example, the reaction written as... 

The order of basicities of alkoxides is opposite to the order of nucleophihcity. Thus, fert-butoxide ion is a stronger base than ethoxide ion. Steric hindrance has little effect on the ease of abstraction of a proton in acid-base reactions. Steric repulsions are less severe when the base approaches a small hydrogen atom than when it approaches the more crowded environment at a tetravalent carbon atom.
