Why is butylamine a stronger base than ammonia?
Alkylamines (like butylamine) are stronger bases than ammonia, as there is a higher electron density on the nitrogen atom. This is because the alkyl group is electron releasing.
What is the pH of diethylamine?

Are amine groups acidic?
Although amines are normally considered to be bases, primary and secondary amines are also very weakly acidic. In other words, amines are amphoteric compounds (p. 97). The conjugate base of an amine is called an amide (not to be confused with amide derivatives of carboxylic acids).
Which amine is more basic?
Amine Answers The amide ion is the strongest base since it has two pairs of non-bonding electrons (more electron-electron repulsion) compared to ammonia which only has one. Ammonium is not basic since it has no lone pair to donate as a base.
Is butylamine a base?
Butylamine is a base (Kb = 3.98×10-4). Hydrochloric acid is a strong acid, so it will convert the butylamine into the butylammonium ion by a neutralization reaction.
