Organosilicon polymers containing Si-O-Si linkage is called

Options

A. Silicates
B. Silicones
C. Glass
D. Silica

Answer

To solve the question regarding the term for organosilicon polymers containing Si-O-Si linkages, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Components**:
- The question refers to organosilicon polymers, which are compounds that contain silicon (Si) and organic groups (R).
- The specific linkage mentioned is Si-O-Si, which indicates a connection between silicon atoms through oxygen.

2. **Identify the Options**:
- The options given in the transcript include silicates, silicons, glass, and silica. We need to analyze each of these terms to find the correct one.

3. **Analyze Silicates**:
- Silicates are compounds where the anions are typically SiO4^4- tetrahedra. They do not specifically refer to organosilicon polymers with Si-O-Si linkages. Therefore, silicates are not the correct answer.

4. **Analyze Silicons**:
- Silicons are defined as synthetic organosilicon polymers that contain repeated SiO units held together by Si-O-Si linkages. This matches the description given in the question. Thus, silicons are a strong candidate for the answer.

5. **Analyze Glass**:
- Glass is primarily made from silica (SiO2) and does not specifically refer to organosilicon polymers. It consists of silicon and oxygen in a network structure but does not have the Si-O-Si linkage characteristic of organosilicon polymers. Therefore, glass is not the correct answer.

6. **Analyze Silica**:
- Silica refers to silicon dioxide (SiO2) and is a component of glass. It does not represent organosilicon polymers. Hence, silica is also not the correct answer.

7. **Conclusion**:
- After analyzing all the options, the term that correctly describes organosilicon polymers containing Si-O-Si linkages is **silicons**.

### Final Answer:
The organosilicon polymers containing Si-O-Si linkage are called **silicons**.
