Which of the following properties correctly explain `SiO_(2)`?

Options

A. Linear, basic
B. Tetrahedral, acidic
C. Tetrahedral, basic
D. Linear, acidic

Explanation

To determine which properties correctly explain SiO₂ (silicon dioxide), we can break down the information provided in the video transcript into a structured solution.

### Step-by-Step Solution:

1. **Identify the Structure of SiO₂**:
- SiO₂, commonly known as silica, has a tetrahedral structure. Each silicon atom is covalently bonded to four oxygen atoms, forming a three-dimensional network.
- **Hint**: Remember that the tetrahedral arrangement is a key characteristic of silicon's bonding in SiO₂.

2. **Understand the Nature of SiO₂**:
- SiO₂ is slightly acidic in nature. This is because it does not dissociate completely in aqueous solutions, which means it can react with strong bases, indicating its weak acidic properties.
- **Hint**: Consider how the behavior of SiO₂ in solution reflects its acidic nature.

3. **Recognize the Bonding and Network Formation**:
- The structure of SiO₂ is not just a simple molecule; it forms a continuous network of silicon and oxygen atoms. This network structure contributes to its stability and physical properties.
- **Hint**: Think about how the network structure influences the physical properties of SiO₂, such as its hardness and melting point.

4. **Summarize the Properties**:
- The two properties that correctly explain SiO₂ are:
- It has a tetrahedral structure.
- It exhibits weak acidic behavior.

5. **Conclusion**:
- Based on the analysis, the correct properties that explain SiO₂ are that it is tetrahedral in structure and slightly acidic.

### Final Answer:
The properties that correctly explain SiO₂ are:
- Tetrahedral structure
- Slightly acidic nature
