The correct statement regarding the basicity of arylamines is
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
Arylamines are generally more basic than alkylamines, because of aryl group
Arylamines are generally more basic than alkylamines because the nitrogen atom in arylamines is sp-hydridized.
Arylamines are generally more basic than alkylamines because the nitrogen atom in arylamines is sp-hydridized.
