Question

Teflon is a polymer of (a) tetrafluorethylene (b) tetraiodoethylene (c) tetrabromoethylene (d) tetrachloroethylene

Short answer

The polymer of teflon is (a) tetrafluorethylene.

Step-by-step solution

Identify the Question

We need to identify which monomer teflon is polymerized from. The question presents four options, and we must choose the correct one.

Recall Polymer Basics

Polymers are large molecules formed by the repeated linkage of small molecules known as monomers. Knowing the structure of teflon will help determine its monomer.

Examine Teflon Structure

Teflon is known chemically as Polytetrafluoroethylene (PTFE). Its structure consists of repeating units derived from tetrafluorethylene, which implies that the polymer is made by polymerizing tetrafluorethylene monomers.

Choose the Correct Monomer

Based on the name and structure of teflon (PTFE), the correct monomer that forms teflon is tetrafluorethylene. This is option (a) in the given list.

Key concepts

Teflon

Teflon is a remarkable material known for its non-stick properties and resistance to heat and chemicals. Its scientific name is Polytetrafluoroethylene (PTFE), and it is widely used in cookware, industrial applications, and even clothing for its durability and low friction. Teflon’s characteristics stem from its unique molecular structure, where fluorine atoms surround carbon atoms, creating a strong, slippery surface. This structure is not only responsible for its non-reactivity but also makes Teflon highly resistant to temperature and environmental factors, contributing to its extensive use in various fields.

Monomers

Monomers are small molecules that serve as the building blocks for polymers. Imagine them as individual Lego pieces that link together to form a complex structure. In the case of Teflon, the monomer involved is tetrafluoroethylene. Each monomer connects in a chain during the process of polymerization, creating the larger structure known as a polymer. Understanding monomers is essential when studying polymers, as they determine the properties and function of the resulting polymer, affecting everything from strength and flexibility to thermal and chemical resistance.

Polymerization

Polymerization is the chemical process in which monomers join to form a polymer. During this process, monomers like tetrafluoroethylene link together through chemical bonds, creating long chains that make up the polymer. There are different types of polymerization, including:

• Addition Polymerization: monomers add together without the loss of any atoms.
• Condensation Polymerization: involves the loss of small molecules like water.

For Teflon, addition polymerization occurs, resulting in a robust and stable polymer that boasts features like non-stick surfaces and high resistance to extreme conditions.

Tetrafluoroethylene

Tetrafluoroethylene is a chemical compound that plays a crucial role as the monomer in the formation of Teflon. It is a gaseous substance composed of carbon and fluorine atoms, notably represented by the formula \(C_2F_4\). When tetrafluoroethylene undergoes polymerization, it forms polytetrafluoroethylene (PTFE), the scientific term for Teflon.
The presence of fluorine atoms in tetrafluoroethylene contributes to the extraordinary stability and low friction of Teflon, making it ideal for applications requiring chemical inertness and temperature resistance. Its ability to polymerize efficiently highlights its importance not only in the production of Teflon but also in various industrial processes involving fluorinated materials.
