H + H-C: H:ci: -CC-H H ethylene Vinyl chloride is the monomor molecule trom which polyvinylchloride (PVC) is made. PVC is one of the most commonly used polymers in construction engineering and consists of a long chain of the molecule on the right, chloroethane. A balanced chemical reaction for the reaction is shown in this image to make chloroethane. What is the enthalpy of this reaction? Use the following bond dissociation energies to perform your calculation: a C-Cpl bond = 264 kJ/mol; an H-CI bond 431 kJ/mol; a C-H bond 413 kJ/mol; a C-Cl bond - 338 kJ/mol 208 kJ/mol 56 kJ/mol -56 kJ/mol --208 kJ/mol
