Explain the following giving a reason in each case

(i) Why is an alkylamine more basic than ammonia?

(ii) Why do primary amines have higher boiling points than the tertiary amines?

Best Answer

(i) Alkylamine is more basic than ammonia because in aliphatic amines, the electron releasing alkyl group stabilize their ammonium cations by dispersing the positive charge and in parent amine make the nitrogen unshared electrons more available for sharing with a proton

alkylamine more basic than ammonia

(ii) The boiling points of primary amine are higher than the tertiary amines because strong intermolecular hydrogen bonding takes place between the molecules of primary amine.

amines have higher boiling
