a) How will you convert an alkyl halide to a primary amine whose molecule has one more carbon atom than the alkyl halide used?
b) Why are amines more basic than comparable alcohols?
b) Why are amines more basic than comparable alcohols?
Solution
(a) The nitrile route adds a carbon:
(b) Nitrogen's lower electronegativity leaves its lone pair more available for protonation, and R–NH tolerates the charge better than R–OH — hence amines are stronger bases.
