Organic chemistry (OC) appears to be an unstructured and confusing subject to many learners. Reaction mechanisms often seem to be an additional challenge rather than a helpful guideline. Comparable problems were also found for OC as a science at the beginning of the 20th century. One turning point was the systematic application of physical principles on organic reactions through Ingold and coworkers. Kinetic measurements implied for example that in nucleophilic substitution reactions the elimination of the leaving group and the attack of the nucleophile could either occur at the same time or stepwise. In this work the historic insights are made accessible for school lessons by easy experiments suitable for school students. A fictional audio diary of Hilda Ingold is proposed as a history lift to make learners realize that in principle different reaction pathways are possible for one reaction type. [ABSTRACT FROM AUTHOR]
