Find the natural polymer among the following

Options

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

Answer

To find the natural polymer among the given options, we can follow these steps:

### Step 1: Understand the Definition of Natural and Synthetic Polymers
Natural polymers are substances that occur naturally in the environment, typically derived from plants or animals. Synthetic polymers, on the other hand, are man-made and produced through chemical processes.

### Step 2: Analyze the Given Options
We need to evaluate each of the options provided to determine whether they are natural or synthetic polymers.

1. **Nylon**: This is a synthetic polymer, specifically a polyamide, created through the polymerization of amides. It is not found in nature.

2. **Teflon**: This is also a synthetic polymer, known as a fluoropolymer. It is produced through the polymerization of tetrafluoroethylene and is not naturally occurring.

3. **PVC (Polyvinyl Chloride)**: This is another synthetic polymer made from the polymerization of vinyl chloride. It is manufactured and does not exist in nature.

4. **Cellulose**: This is a natural polymer found in the cell walls of plants. It is composed of glucose units and is a major component of plant structure.

### Step 3: Identify the Natural Polymer
From the analysis, we can conclude that among the options provided, **cellulose** is the only natural polymer.

### Step 4: Final Answer
Therefore, the natural polymer among the given options is **cellulose**.
