Which of the given polymres is a natural polymer

Options

A. Polyester
B. Glyptal
C. Starch
D. Nylon - 2 - Nylon - 6

Answer

To determine which of the given polymers is a natural polymer, we can follow these steps:

### Step 1: Understand the Types of Polymers
Polymers can be classified into two main categories: natural polymers and synthetic polymers. Natural polymers are those that occur in nature, while synthetic polymers are man-made.

### Step 2: Identify the Given Polymers
The question presents several polymers:
1. Polyester (specifically polyethylene terephthalate)
2. Glyptol
3. Starch
4. Nylon-2 and Nylon-6

### Step 3: Classify Each Polymer
- **Polyester (Polyethylene Terephthalate)**: This is a synthetic polymer made from the reaction of terephthalic acid and ethylene glycol.
- **Glyptol**: This is also a synthetic polymer, commonly used in paints and coatings.
- **Starch**: This is a natural polymer composed of glucose monomer units linked by glycosidic bonds. It is found in many plants, such as potatoes and corn.
- **Nylon-2 and Nylon-6**: Both of these are synthetic polymers made from amino acids and are used in textiles and plastics.

### Step 4: Conclusion
Among the polymers listed, the only natural polymer is **starch**.

### Final Answer
The natural polymer among the given options is **starch**.
