Which of the following is an example of condensation Polymers ?

Options

A. polyethene
B. neoprene
C. teflon
D. nylon

Explanation

To determine which of the given options is an example of condensation polymers, we first need to understand what condensation polymers are. Here's a step-by-step breakdown of the solution:

### Step 1: Define Condensation Polymers
Condensation polymers are formed through a polymerization process where monomers react to form a polymer while eliminating small molecules, typically water or alcohol.

**Hint:** Remember that condensation polymers involve the loss of small molecules during their formation.

### Step 2: Identify Examples of Polymers
We will examine the provided examples to see if they fit the definition of condensation polymers:
1. **Polyethylene**: Formed from the polymerization of ethylene (C2H4). This is an addition polymer, as no small molecules are eliminated during its formation.

**Hint:** Addition polymers do not eliminate any small molecules.

2. **Neoprene**: Formed from the polymerization of chloroprene. Like polyethylene, neoprene is also an addition polymer and does not involve the elimination of small molecules.

**Hint:** Check if the polymerization involves the loss of water or alcohol.

3. **Teflon**: Formed from tetrafluoroethylene. This is another addition polymer, as there is no elimination of small molecules.

**Hint:** Teflon is known for its non-stick properties and is not a condensation polymer.

4. **Nylon 66**: Formed from the reaction of adipic acid and hexamethylenediamine. During the polymerization, a water molecule is eliminated when the carboxylic acid group (-COOH) reacts with the amine group (-NH2).

**Hint:** Look for the elimination of water or other small molecules in the polymerization process.

### Step 3: Conclusion
Based on the analysis:
- Polyethylene, neoprene, and Teflon are addition polymers.
- Nylon 66 is a condensation polymer because it involves the elimination of water during its formation.

Thus, the correct answer is **Nylon 66**.

### Final Answer
**Nylon 66 is an example of a condensation polymer.**
