Options
- A- ! ! [ CH ₂ - CH ₂ ] ! !-_n
- B- ! ! [ CH ₂ - CN CH ] ! !-_n
- C- ! ! [ CH ₂ - Cl CH ] ! !-_n
- D- ! ! [ CF ₂ - CF ₂ ] ! !-_n
Correct answer
C. - ! ! [ CH ₂ - Cl CH ] ! !-_n
Step-by-step solution
Polyvinyl chloride (PVC) is a widely used synthetic plastic polymer. It is water-resistant and durable, making it the primary material used in the manufacture of articles like raincoats, hand bags, vinyl flooring, and water pipes. The monomer of PVC is vinyl chloride ( CH ₂= CHCl ). Upon polymerization, it forms PVC, which has the repeating unit - [ CH ₂ - Cl CH ]_n- . Answer: - ! ! [ CH ₂ - Cl CH ] ! !-_n
