About this person
His groundbreaking work in the 1920s and 1930s on reaction mechanisms and the electronic structure of organic compounds was responsible for the introduction into mainstream chemistry of concepts such as nucleophile, electrophile, inductive and resonance effects, and such descriptors as SN1, SN2, E1, and E2 now known as the Hughes-Ingold symbols. He also was a co-author of the Cahn-Ingold-Prelog priority rules. Ingold is regarded as one of the chief pioneers of physical organic chemistry.
