Answer

The statement that the uses of polymers are dependent on their properties can be demonstrated using polyvinyl chloride (PVC), a polymer derived from vinyl chloride. PVC is known for its durability, chemical resistance, and versatility, which makes it applicable in various industries.

For instance, PVC can be rigid or flexible depending on its formulation, allowing it to be used for plumbing pipes, electrical cables, and flooring. The strength and resistance of PVC to environmental stress make it suitable for outdoor applications without degrading quickly.

Polymer properties such as tensile strength, flexibility, and temperature resistance directly influence its usability in specific contexts. Therefore, understanding these properties is crucial for selecting the right polymer for each application.

Step 3

Draw the structure of a polymer made from one of the above monomers.

Answer

The structure of a polymer made from vinyl chloride can be represented as follows:

        -[CH₂-CHCl]-
        |          |
        -[CH₂-CHCl]-
        |          |
        -[CH₂-CHCl]-

This denotes a repeating unit of polyvinyl chloride (PVC).
