ncerthelp.comBasic Strength of Amines Amines act as Lewis bases due to the presence of lone pair of electrons on the nitrogen atom. More the K b (dissociation constant of base), higher is the basicity of amines. Lesser the pK b‘ higher is the basicity of amines. Aliphatic amines (CH 3 NH 2) are stronger bases than NH 3 due to the electron releasing +/ effect

Amines are classified into aliphatic, alicyclic (Three Bond 2106), and aromatic amines according to the types of hydrocarbons involved, and the all are important curing agents for epoxy resin.
