Plastics arrangement is

Options

A. Linear
B. Cross linked
C. Linear as well as cross linked
D. None of the above

Answer

### Step-by-Step Text Solution

1. **Understanding Plastics**: Plastics are synthetic materials made from polymers, which are long chains of repeating molecular units. These polymers can be arranged in different structures.

2. **Types of Polymer Arrangements**:
- **Linear Polymers**: These are long chains of repeating units that are arranged in a straight line. They can be flexible and are often used in applications where strength and flexibility are required.
- **Cross-Linked Polymers**: In contrast to linear polymers, cross-linked polymers have chemical bonds that link the chains together. This creates a network structure that is typically more rigid and strong.

3. **Comparison of Arrangements**:
- Linear polymers are characterized by their chain-like structure, which allows them to be more flexible and stretchable.
- Cross-linked polymers form a three-dimensional network, which provides them with enhanced strength and stability.

4. **Conclusion**: Given the two types of arrangements, plastics can be categorized as both linear and cross-linked polymers. Therefore, the correct answer to the question about plastic arrangements is that plastics can be both linear and cross-linked.
