http://chemistry2.csudh.edu/rpendarvis/aminrxn.html WebIn the case of making amides from carboxylic acids, the difficulty comes because the carboxylic acid is a stronger acid (pK a ~5) than the ammonium salt (pK a ~10). The result is that there is very little amine and carboxylic acid at equilibrium. so there is very little nucleophile present.
