The correct statement regarding the basicity
of arylamines is :-
(1) Arylamines are generally less basic than
alkylamines because the nitrogen lone-pair
electrons are delocalized by interaction with the
aromatic ring ``\pi`` electron system.
(2) Arylamines are generally more basic than
alkylamines because the nitrogen lone-pair
electrons are not delocalized by interaction with
the aromatic ring ``\pi``electron system.
(3) Arylamines are generally more basic than
alkylamines because of aryl group.
(4) Arylamines are generally more basic than
alkylamines, because the nitrongen atom in
arylamines is sp-hybridized.
