E)none of the above

Quizplus · Accepted Answer

Transition states represent the point along the reaction path where the energy is at a maximum and the structure is not stable; they are characterized by partially formed bonds. Intermediates, on the other hand, are more stable entities that exist between the starting materials and the products in a reaction mechanism, with fully formed bonds.
