Concept Introduction:
Base is defined as species which can give hydroxide ion in the solution. To compare the basicity of anions, the acidity of their conjugate acids needs to be compared. In an acid, if the electronegativity of the atom attached to the acidic proton is increased, the bond between the electronegative atom and hydrogen becomes more polar, this results in increase in the acidic strength.
On increasing the size of the atom attached to the acidic proton, the acidic strength increases. The third factor that determines the acidity of a molecule is its resonance ability. If the charge can be delocalized over several atoms in the acid, it will be more acidic. This effect is enhanced by the presence of additional electronegative atoms.
Good leaving groups are conjugate bases of strong acids.
