Radical and Type Theories in Organic Chemistry (1832-1850) - Lecture 22
Explore the historical development of radical and type theories in organic chemistry from 1832 to 1850 in this 49-minute Yale University lecture. Delve into the work of Wöhler and Liebig on benzaldehyde, which led to a focus on radicals in organic reactions. Examine the rivalry between Liebig and Dumas, and how it influenced the evolution of chemical theories. Uncover the mystery of the chlorinated candle and its impact on substitution reactions. Learn about the persistence of both radical and type theories in modern organic nomenclature. Gain insights into the HOMO-LUMO mechanism of alkene addition and the SOMO mechanism of free-radical chain reactions. Discover how this period reveals more about the psychology and sociology of leading chemists than fundamental chemistry principles.
