Two configurations can actually be envisioned for the transition state in the DMDO epoxidation of (Z)-2-butene, based on analogy with geometric possibilities fitting within the general outline for the transition state in a peroxycarboxylic acid epoxidation of (Z)-2-butene. Draw these geometries for the DMDO epoxidation of (Z)-2-butene. Then, open the molecular models on the book's website for these two possible transition state geometries in the DMDO epoxidation of (Z)-2-butene and speculate as to which transition state would be lower in energy.
