Question

alkyl amine is stronger base than ammonia why?​

Answer 1

${\huge{\color{yellow}{\fcolorbox{aqua}{navy}{\fcolorbox{yellow}{purple}{\rm{Answer}}}}}}$

Because alkyl groups donate electrons to the more electronegative nitrogen. The inductive effect makes the electron density on the alkylamine's nitrogen greater than the nitrogen of ammonium. Correspondingly, primary, secondary, and tertiary alkyl amines are more basic than ammonia.

Answer 2

Answer:

Due to electron releasing nature, the alkyl group (R) pushes electrons towards nitrogen in alkyl amine and thus makes the unshared electron pair more available for sharing with the proton of the acid. Therefore, alkyl amines are more basic than ammonia.
