(a) Interpretation:
It is to be determined whether the given reactant is suitable for a reaction involving ethanol as a solvent with respect to leveling effect.
Concept introduction:
The solvent affects the properties of bases and acids. This effect is referred as leveling effect. For an acid-base reaction, the basicity of the solvent levels or limits the strength of the strong acid. Similarly, the acidity of the solvent levels the strength of the strong base. With respect to the leveling effect, a solvent is unsuitable for a particular reactant R if R is a stronger acid that the solvent’s conjugate acid (i.e., R has the lower pKa) or if R is a stronger base than the solvent’s conjugate base (i.e., the conjugate acid of R has a higher pKa than the solvent).
