Question

The correct statement regarding the basicity of arylamines is:

• A. Arylamines are generally more basic than alkyamines because of aryl group .
• B. Arylamines are generally more basic than alkyamines 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 alkyamines because the nitrogen atom in arylamines is sp-hybridized.
• D. Arylamines are generally less basic than alkyamines

Answer 1

The correct option is D Arylamines are generally less basic than alkyamines


Lone pair of nitrogen is in conjugation with the benzene ring which decreases the availability of electrons on nitrogen hence the basic strength decreases. no such conjugation is found in alkylamine. Thus Arylamines are generally less basic than alkyamines.
