Answer
The product is 2,3-epoxyhexane. The reactant is trans and the product is also trans.
Work Step by Step
Starting with the alkene and the peroxyacid, a one-step reaction gives the epoxide and the acid directly, without any intermediates.
The epoxide ring is formed where the double bond is on carbon 2 and 3. Since, the reactant was trans, the product is also trans.
