Which is the structure of polyvinyl chloride (polychloroethane)?
Correct answer: D. -[H2C-CH-Cl]-
- A. -[CCl2-CCl2]-
- B. -[HCCl-CH-Cl]-
- C. [H2C=CH-Cl]
- D. -[H2C-CH-Cl]-
Explanation
Poly(vinyl chloride) (PVC) is a synthetic resin made from vinyl chloride and is a member of a large family of polymers broadly referred to as "vinyls." The chemical formula for vinyl chloride is H2C=CHCl, and the formula for PVC is (H2C-CHCl)n, where n is the degree of polymerization.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
