Polymer of perfluoroethylene is

Options

A. Polythene
B. PVC
C. Teflon
D. Buna-N

Answer

To solve the question, "What is the polymer of perfluoroethylene?" we can follow these steps:

### Step 1: Understand the Structure of Ethylene
Ethylene is a simple hydrocarbon with the formula \( \text{C}_2\text{H}_4 \), which can be represented as \( \text{CH}_2=\text{CH}_2 \).

**Hint:** Remember that ethylene has a double bond between the two carbon atoms.

### Step 2: Modify Ethylene to Form Perfluoroethylene
Perfluoroethylene is derived from ethylene by replacing all hydrogen atoms with fluorine atoms. Thus, perfluoroethylene can be represented as \( \text{CF}_2=\text{CF}_2 \).

**Hint:** The term "perfluoro" indicates that all hydrogen atoms in ethylene are replaced by fluorine.

### Step 3: Identify the Polymerization Process
Perfluoroethylene undergoes a process called addition polymerization. This process involves the joining of multiple monomer units (in this case, perfluoroethylene) without the loss of any small molecules.

**Hint:** Addition polymerization means that the double bonds in the monomers open up to form long chains without losing any atoms.

### Step 4: Determine the Name of the Polymer
The polymer formed from the polymerization of perfluoroethylene is known as polytetrafluoroethylene (PTFE). It is commonly referred to by its brand name, Teflon.

**Hint:** The prefix "poly-" indicates that it is a polymer, and "tetrafluoroethylene" refers to the monomer used to create it.

### Final Answer
The polymer of perfluoroethylene is **polytetrafluoroethylene (PTFE)**, commonly known as **Teflon**.
