    As in aniline N has a lone pair of electron to dislocate in ring,, that's why it is less basic

    2Thank You

    Rashi Bari 8 years, 2 months ago

    During resonance anilinium ion when gets protonated it exhibits partial double bond character (within benzene ring) which in turn increases its stability and therefore it is more acidic or competitively less basic than amine and ammonia.

    2Thank You

    Amanul Haque 8 years, 2 months ago

    in case of aniline,lone pair of N is in Resonance with ring and this lone pair is not available for donation. As you know lone pair donors are lewis bases hence it is less basic
