what is the order of basicity in amines in aqueous solution ??
The basicity of an amine in aqueous solution depends upon the stability of the ammonium cation, which in turn depends upon a combination of the following three factors:
(1) +I effect of the alkyl group
(2) Extent of hydrogen bonding with water molecules.
(3) Steric effect of the alkyl groups
In aqueous phase, the order is slightly different: 2’> 1’> 3’ > NH3
