Thermal pyrolysis of ethylene dichloride produces ____________________?
Correct answer: B. Vinyl chloride
- A. Trichloroethylene
- B. Vinyl chloride
- C. Ethanol amine
- D. Ethylene oxide
Explanation
On thermal cracking, ethylene dichloride loses hydrogen chloride and forms vinyl chloride, the monomer used to manufacture PVC. The key reaction is C2H4Cl2 → C2H3Cl + HCl.
