Cyclohexene is treated with meta-chloroperoxybenzoic acid () in dichloromethane. The main product is

  1. Acyclohexanone
  2. Bcyclohexene oxide (7-oxabicyclo[4.1.0]heptane)
  3. Ccyclohexanol
  4. Dtrans-cyclohexane-1,2-diol

Answer: B

A peroxy acid transfers an oxygen atom to the bond in a single concerted step. The product is the epoxide. The diol would form only if the epoxide were later opened by aqueous acid.
