State reasons for the following:
Aliphatic amines are stronger bases than aromatic amines.

Text Solution

Verified by Experts

In aliphatic amines, the alkyl group increase the electron density on N atom due to (+I) inductive effect, hence making the `-NH_(2)` group more basic and likely to attract proton.

Whereas, in aromatic amine the lone pair of electrons is involved in the resonance of benzene ring hence unavailable for showing basic character. So, aromatic amines are less basic than aliphatic amines.
