Find the natural polymer among the following

Options

A. Nylon
B. Teflon
C. PVC
D. Cellulose

Answer

To solve the question of identifying the natural polymer among the given options, we can follow these steps:

### Step 1: Understand the Types of Polymers
Polymers can be classified into three categories based on their origin:
1. **Natural Polymers**: These are obtained directly from nature. Examples include proteins, starch, and cellulose.
2. **Synthetic Polymers**: These are man-made and synthesized through chemical processes. Examples include nylon, Teflon, and PVC (polyvinyl chloride).
3. **Semi-synthetic Polymers**: These are derived from natural sources but modified chemically. An example is nitrocellulose.

### Step 2: Analyze the Given Options
The question provides four options:
1. **Nylon**: A synthetic polymer made from the polymerization of amides.
2. **Teflon**: A synthetic polymer made from tetrafluoroethylene.
3. **PVC (Polyvinyl Chloride)**: A synthetic polymer made from the polymerization of vinyl chloride.
4. **Cellulose**: A natural polymer found in the cell walls of plants.

### Step 3: Identify the Natural Polymer
From the analysis:
- **Nylon**, **Teflon**, and **PVC** are all synthetic polymers.
- **Cellulose** is the only polymer that is naturally occurring and derived from plants.

### Conclusion
The natural polymer among the given options is **Cellulose**.

### Final Answer
**Cellulose** is the natural polymer among the options provided.
