Hammond Postulate
Related species that are similar in energy are also similar in structure. The structure of the transition state resembles the structure of the closest stable species.
-transition state for endothermic rxns resembles the product, exothermic the reactant.
-bromination transition state is closest to product. Thus reactivity very closely related to end-product stability (i.e. stability=speed).
