Problem

Consider the following reaction:

(h) Is the transition state closer in structure to the reactants or products? Explain.

 

Solution

We’re being asked to determine if the transition state for the reaction is closer in structure to the reactants or products. We’re given the following energy diagram:



Recall that a transition state is the highest energy point in an energy diagram. According to the Hammond Postulate, transition states most closely resemble the species with the higher energy.
