In general, methylamine (CH3NH2) is a stronger base than ammonia (NH3) and dimethylamine ((CH3)2NH) is a stronger base than methylamine. However, in water, triethylamine ((CH3CH2)3N) which should be even stronger based on stronger inductive effect, is a weaker base than dimethylamine or methylamine. Explain why triethylamine is a weaker base than dimethylamine or methylamine.
