Teflon and neoprene are

Options

A. copolymers
B. monomers
C. homopolymers
D. condensation polymers.

Answer

To determine the classification of Teflon and neoprene, we need to analyze their structures and the process of their formation.

### Step-by-Step Solution:

1. **Identify the Chemical Structure of Teflon:**
- Teflon is known as polytetrafluoroethylene (PTFE).
- The monomer used to make Teflon is tetrafluoroethylene (C2F4).
- The polymerization of tetrafluoroethylene results in a long chain of carbon atoms, each bonded to fluorine atoms.

2. **Identify the Chemical Structure of Neoprene:**
- Neoprene is derived from the monomer chloroprene, which is 2-chloro-1,3-butadiene (C4H5Cl).
- The polymerization of chloroprene leads to a long chain structure where the chlorine atom remains attached to the carbon chain.

3. **Determine the Type of Polymerization:**
- Both Teflon and neoprene are formed through addition polymerization, where the same type of monomer is used repeatedly to form a long chain.
- In Teflon, the repeating unit is derived from tetrafluoroethylene, while in neoprene, it is derived from chloroprene.

4. **Classify the Polymers:**
- **Homopolymers:** These are polymers made from one type of monomer. Since both Teflon and neoprene are made from a single type of monomer (tetrafluoroethylene for Teflon and chloroprene for neoprene), they are classified as homopolymers.
- **Copolymers:** These are made from two or more different types of monomers. Since both Teflon and neoprene do not fit this definition, they cannot be classified as copolymers.

5. **Conclusion:**
- Based on the analysis, both Teflon and neoprene are classified as homopolymers.

### Final Answer:
Teflon and neoprene are **homopolymers**.
