Sir Christopher Ingold’s contribution to organic chemistry appears in every organic chemistry textbook. Ingold described the two types of nucleophilic substitution (SN1 and SN2) for the first time. During and after World War II, Ingold’s contribution to organic chemistry started to be recognized. He published “Structure and Mechanism in Organic Chemistry” book in 1953. Following the publication of this important organic chemistry book, he received a few medals, awards, and honorary degrees. He was knighted in 1958. The Cahn Ingold Prelog (CIP) method was published in 1956, and it is still used in organic chemistry to name the stereoisomers of a molecule. Sir Christopher Ingold became a fierce rival to the famous organic chemist Sir Robert Robinson. In this presentation, I will discuss the papers relevant to the rivalry between Sir Christopher Ingold and Sir Robert Robinson.
