Recently there was a major accident in Ohio where a train carrying vinyl chloride (1-chloroethene) was derailed and most of the contents spilled. Vinyl chloride is used to make the polymer, polyvinyl chloride (PVC), which is used in PVC pipes. Using an appropriate radical initiator and arrows to show electron movement, provide a reasonable mechanism to demonstrate how vinyl chloride can be converted to PVC, the overall reaction is shown below. Include in your mechanism, your initiation, propagation, and termination steps
