This postulate can be used to explain the directing effects of substituents on benzilic acid rearrangements, and the greater regioselectivity in bromination of alkanes compared with chlorination of alkanes. It relies heavily on transition-state theory, and works best on highly endothermic or highly exothermic reactions.  FTP, what is this postulate, which states that the structure of a transition state more resembles either the starting material or product depending on which one is closer in energy to the transition state?
