Description: (British Chemist Known for His Pioneering Work on the Electronic Structure and Reaction Mechanisms of Organic Compounds)
Sir Christopher Kelk Ingold was a renowned British chemist who made significant contributions in the field of organic chemistry during the 1920s and 1930s. His pioneering work focused on elucidating reaction mechanisms and understanding the electronic structure of organic compounds. Ingold introduced key concepts such as nucleophile, electrophile, inductive and resonance effects, as well as important descriptors like SN1, SN2, E1, and E2. He also collaborated on the development of the Cahn–Ingold–Prelog priority rules, solidifying his legacy as a chief pioneer of physical organic chemistry.
