Amines - Result Question 5
####7. The correct statement regarding the basicity of arylamines is
[2016]
(a) Arylamines are generally less basic than alkylamines because the nitrogen lone-pair electrons are delocalized by interaction with the aromatic ring $\pi$ electron system.
(b) 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.
(c) Arylamines are generally more basic than alkylamines because of aryl group. (d) Arylamines are generally more basic than alkylamines, because the nitrogen atom in arylamines is $s p$-hybridized.
Show Answer
Solution:
- (a) Arylamines are generally less basic than alkylamines due to following factors:
(i) Due to resonance in aromatic amines.
(ii) Lower stability of anilinium ion.
