Question:
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 ringπelectron system.
arylamines are generally less basic than alkylamines because the nitrogen lone-pair electrons are delocalized by interaction with the aromatic ringπelectron system.
arylamines are generally more basic than alkylamines, because the nitrogen atom in arylamines is sp-hybridized.
arylamines are generally more basic than alkylamines because of aryl group.
Solution:
Arylamines are generally less basic than alkylamines because the nitrogen lone-pair electrons are delocalized by interaction with the aromatic ring πelectron system which makes electrons less available. While in alkyl amines, the +I electron releasing effect of the alkyl group makes it strongly basic. Thus, option B is correct.
