Question
The correct statement regarding the basicity of aryl amines is:
Options
A.
Aryl amines are generally less basic than alkyl amines because the nitrogen lone-pair electrons aredelocalized by interaction with the aromatic ring π electron system.
B.
Aryl amines are generally more basic than alkyl amines because the nitrogen lone-pair electrons are notdelocalized by interaction with the aromatic ring π electron system.
C.
Aryl amines are generally more basic than alkyl amines because of aryl group.
D.
Aryl amines are generally more basic than alkyl amines, because the nitrogen atom in aryl amines is sp-hybridized.
Solution
Here lone pair is in conjugation with double bond so basic strength decreased
R - NH2 (No conjugation)
