Alkyl ammonium ions, R3NH+ X-, have pKa values in the range of 10-11 (ammonium ion, H4N+ X-, has a pKa ~ 9.3) The ammonium ions of aryl amines and heterocyclic aromatic amines are considerably more acidic than alkyl amines (pKa < 5). The nitrogen lone pair is less basic if it is in an sp2 hybridized ...
