WebIn this case, the second intermediate is more stable because of resonance: a lone pair of electrons on the Cl can be delocalized into the vacant p orbital on the C. This is not ideal, because it puts a + charge on the Cl. But to the extent that it happens, it lowers the energy of the intermediate. WebThe production of PVC involves several stages: a) ethene is converted into 1,2-dichloroethane. b) 1,2-dichloroethane is cracked to chloroethene (vinyl chloride) c) …
