In Elaster, intermolecular force are

Options

A. Nil
B. Weak
C. Strong
D. Very strong

Answer

To answer the question about the intermolecular forces in elastomers, we can break down the solution into the following steps:

### Step-by-Step Solution:

1. **Understanding Elastomers**:
- Elastomers are a type of polymer that are rubber-like and have elastic properties. They can stretch and return to their original shape.

2. **Classification of Polymers**:
- Polymers can be classified based on the strength of intermolecular forces. The categories typically include:
- Thermosetting polymers (strongest intermolecular forces)
- Fibers (strong intermolecular forces)
- Thermoplastics (moderate intermolecular forces)
- Elastomers (weakest intermolecular forces)

3. **Intermolecular Forces in Elastomers**:
- In elastomers, the polymer chains are held together by the weakest intermolecular forces. These forces are not strong enough to prevent the chains from moving past each other, which allows for the elastic properties.

4. **Conclusion**:
- Based on the classification and the nature of the intermolecular forces in elastomers, the correct answer to the question is that the intermolecular forces in elastomers are **weak**.

### Final Answer:
- The intermolecular forces in elastomers are **weak**.
