    ok sir thank you , but in case of aromatic amines....?

    eduncle-logo-app

    sahiba in aromatic amine say aniline the lone pair on nitrogen take part in resonance so it is not available for donation..so here basicity of aniline is less

    eduncle-logo-app

    also pkb value if aniline is quite high

    eduncle-logo-app

    for bridge compounds?

    eduncle-logo-app

    see always check whether lone pair is available or not for donation...if it is available then it is more basic..you know lewis base is electron pair donor

    eduncle-logo-app

    yes sir , I gotted.

    okk sahiba...enjoy your study😊

    got sahiba,the basicity order reverses in both the phase in gaseous phase the basicity order is 3 degree greater tha 2 degree gretaer tha 1 degree as here inductive effect dominance but in aqueous phase solvation effect dominances...1 degree gretaer than 2 greater tha 3rd...and overall order changes..overall 2 degree is most stable

    see basicity order of amines confuses you because the overall basicity order of amines is due to its basicity in gaseous pahse and aqueous phase
