Answer
The product is 1,2-epoxycyclodecane.
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 so on carbon 1 and 2. Since the reactant is trans, the product is also trans. Moreover, since there is a chiral product, there is a racemic mixture.
