When trans-hex-3-ene is treated with PhCO₃H, the major organic product is ________. A) a meso epoxide B) a 1:1 mixture of enantiomeric epoxides C) a meso diol D) a 1:1 mixture of enantiomeric diols E) hexan-3-ol

Question

Quizplus · Accepted Answer

PhCO₃H is a peracid that promotes epoxidation of alkenes. The resulting epoxide will form with stereospecificity, meaning that both oxygen atoms will be trans to each other just like in the starting alkene. Since the starting alkene is not symmetric, the resulting epoxide will be asymmetric and thus enantiomeric. Therefore, the major product will be a 1:1 mixture of enantiomeric epoxides (choice B).
