Solution
The factor effecting the basicity of amines are gradually for aromatic amines they are less basic than aliphatic amines due :-
(1) The lone pair of electrons on the nitrogen atom is declocalised into benzene rings as a result,the lone pair of electrons is less available for donation to an acid.
(2) Electron withdrawing group attached to the benzene ring decreases the basicity of amines. Eg:- refer to image
Due to more - I effect of halogen(i.e Bromine),the compound 2,4,6 tribromo aniline is less basic.
