Selected bond dissociation enthalpies are given in this table. Polyvinyl chlorid

Question

Selected bond dissociation enthalpies are given in this table. Polyvinyl chloride (PVC) is one of the most commercially important polymers. PVC is made by addition polymerization of vinyl chloride (C2 H3 Cl). Vinyl chloride is synthesized from ethylene (C2H4) in a two -step process involving the following equilibria: Equilibrium 1: C2H4(g) + Cl2(g) C2 H4 Cl2(g) Equilibrium 2: C2 H4 Cl4(g) C2 H3 Cl(g) + HCl(g) What are the C - C bond orders in and C2 H4 Cl and C2H3Cl, respectively ? Express your answers numerically separated by commas. This part will be visible after you complete previous item(s). This part will be visible after you complete previous item(s). This part will be visible after you complete previous item(s).

Explanation / Answer

We Know that :      C2H4 is aEthylene where the C-C bond order is 2 , C2H4Cl2 is Di-chloroethylenewhere the C-C bond order is 1.         C2H3 Cl                              Doublebond equivalent = 2 + 1 - ( 3+1 ) / 2                                                                  = 3 - 2                                                                     =1     one C=C in the molecule .                                                 Sorry the remaining questions are not visible. If u post them i tryto solve the Remaining ones.              Ans for the Firstbit is 1,2
