About this Item

This seminal paper published by chemist George S. Hammond introduced the concept now widely known as "Hammond's Postulate" - a principle explaining the relationship between the structure of a transition state and the stability of reactants and products in a chemical reaction, allowing for qualitative prediction of reaction rates based on their energy profiles. Key points about Hammond's Postulate: (1) Transition state similarity: According to the postulate, if a reaction has a relatively small energy barrier (a low activation energy), the transition state will resemble the reactant more than the product, and vice versa. (2) Structure-reactivity correlations: This concept allows chemists to predict how changes in reactant structure will affect the reaction rate by considering the structure of the transition state. (3) Qualitative nature: While the postulate is based on transition state theory, its key strength lies in its qualitative nature, making it easy to apply in various chemical scenarios.
