Ammonia, NH3, is also a weak base with Kp = 1.8x10-5. Which of the following is the best explanation for why dimethylamine is a stronger base than ammonia? The question as stated is incorrect, ammonia is a stronger base than dimethylamine because of the bigger lone pair of electrons on the N of ammonia compared to the N on dimethylamine. The hydrogens on ammonia are more electronegative than the methyl groups on dimethylamine, making ammonia a weaker base than dimethylamine. The two methyl groups on dimethylamine are more electronegative than the hydrogens on ammonia and make dimethylamine a stronger base. The two methyl groups on dimethylamine that replace hydrogens on ammonia are electron rich and donate electron density to the N making dimethylamine a stronger base.
