The widely used PVC is polymerized product of;
Correct answer: D. CH2=CHCI
- A. CH2=CH2
- B. CH2=CCI2
- C. CICH2=CH2CI
- D. CH2=CHCI
Explanation
Polyvinyl Chloride (PVC) is produced by the polymerization of vinyl chloride monomers, represented by the structure CH2=CHCI. This monomer undergoes polymerization to form the repeating units in PVC. The other options represent different chemical compounds: ethylene forms polyethylene, vinylidene chloride is used for Saran wrap, and 1,2-dichloroethane is not used for PVC production.
