Answer:
Aliphatic amines are stronger bases than aromatic amines due to following reasons: (a) Electron pair on the nitrogen atom of aromatic amines is involved in conjugation with the electron pairs of the ring as follows (b) Anilinium ion obtained by accepting a proton is less stabilized by resonance.
The strength of a base is determined by its ability to donate the lone pair of electrons. In case of aromatic amines, the lone pair of electrons on nitrogen is in resonance with the benzene ring. ... This makes aromatic amines weak bases.
