Question

The correct statement regarding the basicity of arylamines is:

• 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 sp-hybridized

Answer 1

The correct option is 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


Lone pair of nitrogen is in conjugation with the benzene ring which decreases the availability of electrons on nitrogen hence the basic strength decreases.
