Which S_N2 reaction would you expect to take place most rapidly? Assume that the concentrations of the reactants and the temperature are the same in each instance:

Question

Quizplus · Accepted Answer

In order to determine which reaction would take place most rapidly, we need to look at the activation energy required for each reaction. The activation energy is represented by the height of the energy barrier in the reaction diagram. From the given reaction diagrams, we can see that reaction A has the lowest activation energy barrier, indicating that it will proceed most rapidly.
