You might think that all carboxylic acids would have the same strength because each depends on the delocalization of the negative charge around the -COO - group to make the anion more stable, and so m...You might think that all carboxylic acids would have the same strength because each depends on the delocalization of the negative charge around the -COO - group to make the anion more stable, and so more reluctant to re-combine with a hydrogen ion. The nitrogen is still the most electronegative atom in the molecule, and so the delocalized electrons will be attracted towards it, but the intensity of charge around the nitrogen is nothing like what it is in, say, an ammonia molecule.
