Open Yale CoursesCHEM 125: Freshman Organic ChemistryLecture 21 - Berzelius to Liebig and Wöhler (1805-1832)<< previous session| next session >>Overview:The most prominent chemist in the generation following Lavoisier was Berzelius in Sweden. Together withGay-Lussac in Paris and Davy in London, he discovered new elements, and improved atomic weights andcombustion analysis for organic compounds. Invention of electrolysis led not only to new elements but alsoto the theory of dualism, with elements being held together by electrostatic attraction. Wöhler's report on thesynthesis of urea revealed isomerism but also persistent naiveté about treating quantitative data. In theircollaborative investigation of oil of bitter almonds Wöhler and Liebig extended dualism to organic chemistryvia the radical theory.Problem sets/Reading assignment:Reading assignments, problem sets, PowerPoint presentations, and other resources for this lecture can be
