The correct statement regarding the basicity of arylamines is .

Options

A. arylamines are generally more basic than alkyl amines, because the nitrogen atom in arylamines is sp-hydridized.
B. Arylamine are generally less basic than alkyl amine because the nitrogen lone pair electrons are delocalized by interaction with the aromatic ring `pi`-electron system.
C. Arylamines are generally more basic than alkyl amines because the nitrogen lone-pair electrons are not delocalized by interation with the aromatic ring `pi`-electron system.
D. Arylamines are generally more basic than alkyl amines because of aryl group.

Answer

B

Explanation

Dilocalised lone pair of nitrogen atom aryl amine with benzene ring in aryl amine.
`RNH_2rarr`lone pair of electrons of nitrogen atom are not delocalized in alkyl amine.
