Question

Polyvinyl chloride (PVC) is one of the most commercially important polymers. PVC is made by addition polymerization of vinyl chloride (C2H3Cl). Vinyl chloride is synthesized from ethylene (C2H4) in a two-step process involving the following equilibria: (What are the bond orders of these)
  • Equilibrium 1: C2H4(g)+Cl2(g)?C2H4Cl2(g)
  • Equilibrium 2: C2H4Cl2(g)?C2H3Cl(g)+HCl(g)
