Physical Properties of Amines
The carbon-nitrogen triple bond is reduced using hydrides to give a primary amine. For example, with ethanenitrile you get ethylamine The reduction of nitriles using hydrogen and a metal catalyst
The more ammonia there is in the mixture, the more the forward reaction is favoured..
Amines as Bases
Aliphatic amines are stronger bases than aromatic amines because of the resonance in aromatic amines
Electron-donating groups increase the basicity of amines, and electron-withdrawing groups decrease their basicity , and amines are stronger bases than amides
