The correct statement regarding the basicity of aryl amines is:

  1. A
    Aryl amines are generally more basic than alkyl amines because the nitrogen lone-pair electrons are not delocalized by interaction with the aromatic ring electron system.
  2. B
    Aryl amines are generally more basic than alkyl amines because of aryl group.
  3. C
    Aryl amines are generally more basic than alkyl amines, because the nitrogen atom in aryl amines is -hybridized.
  4. D
    Aryl amines are generally less basic than alkyl amines because the nitrogen lone-pair electrons are delocalized by interaction with the aromatic ring electron system.

Solution & Step-by-step Explanation

In aryl amines (like aniline), the lone pair of electrons on the nitrogen atom is in conjugation with the electron system of the benzene ring. This delocalization makes the lone pair less available for protonation. In alkyl amines, there is no such resonance, and the effect of alkyl groups increases electron density on nitrogen, making them more basic.
