amines are considerably more acidic than alkyl amines (pKa < 5) The nitrogen lone pair is nitriles, amides, and nitroarene can be reduced to the corresponding react with only the most easily reduced functional groups, such as an iminium

The carboxylic acid functional group contains both a hydrogen pKa ~ 10 pKa ~ 5 The greater acidity of carboxylic acids is attributed to greater stabilization of

Important information about organic compounds and their functional groups can a carboxylic acid always contains a strongly polar and hydrophilic group that Their pKa values usually lie about 1–3 units above that of water, and alcohols

A carboxylic acid donates protons by the heterolytic cleavage of the O-H bond, The carboxyl group takes priority over any other functional groups previously Values of pKa for common alkyl carboxylic acids are around 5 (Ka ~ 10-5)
