Question

Why is an alkylamine more basic than ammonia ?

Answer 1

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:

Explanation:

Alkyl amines have alkyl groups, which have strong +I effect.So,they push the electron density towards nitrogen atom, making the bond more polar.As a result,the lone pair of electrons becomes more available for donation from nitrogen in alkyl amines.But,in ammonia,no +I effect group is there, hence the polarity of bond is less, hence being less basic.Hope you understood
