A polymer is resistant to heat and chemical attack and is also used for coating articles and cookwares to make them non - sticky. The monomer of this polymer is

Options

A. mono chlortifluoroethylene
B. tetrafluoroethylene
C. chloroprene
D. vinyl chloride

Answer

To solve the question, we need to identify the polymer described and its corresponding monomer. Let's break it down step by step.

### Step 1: Identify the Properties of the Polymer
The question states that the polymer is resistant to heat and chemical attack and is used for coating articles and cookware to make them non-sticky.

**Hint for Step 1:** Think about common polymers that are known for their heat resistance and non-stick properties.

### Step 2: Recognize the Polymer
Based on the properties mentioned, the polymer is likely Teflon, which is also known as polytetrafluoroethylene (PTFE). Teflon is widely used in cookware for its non-stick properties and is known for its durability against heat and chemicals.

**Hint for Step 2:** Recall the name of the polymer that is often associated with non-stick cookware.

### Step 3: Identify the Monomer
The monomer of Teflon (polytetrafluoroethylene) is tetrafluoroethylene. This monomer consists of two carbon atoms and four fluorine atoms.

**Hint for Step 3:** Consider the structure of Teflon and identify the simplest unit that can polymerize to form it.

### Step 4: Write the Chemical Structure of the Monomer
The chemical structure of tetrafluoroethylene can be represented as:
\[ \text{C}_2\text{H}_2\text{F}_4 \]
This indicates that there are two carbon atoms (C) and four fluorine atoms (F) in the monomer.

**Hint for Step 4:** Visualize the arrangement of atoms in tetrafluoroethylene to understand how it polymerizes to form Teflon.

### Conclusion
The monomer of the polymer Teflon is tetrafluoroethylene.

**Final Answer:** The monomer of the polymer Teflon is tetrafluoroethylene.
