Which of the following will not give a white pt. when `AgNO_(3)` is added to its solution?

Options

A. `C Cl_(4)`
B. `NaCl`
C. `MgCl_(2)`
D. KCl

Explanation

To determine which of the given compounds will not produce a white precipitate when silver nitrate (AgNO₃) is added to its solution, we need to analyze the nature of the compounds involved.

### Step-by-Step Solution:

1. **Understanding the Reaction**:
- Silver nitrate (AgNO₃) reacts with halides (like Cl⁻, Br⁻, I⁻) to form a white precipitate of silver halide (AgX). For example, AgNO₃ + NaCl → AgCl (white precipitate) + NaNO₃.

2. **Identifying the Compounds**:
- We need to look at the options provided (though they are not listed here, we will assume common organic and inorganic compounds).

3. **Analyzing CCl₄**:
- Carbon tetrachloride (CCl₄) is a covalent compound and is non-polar. It does not dissociate into ions in solution, which means it cannot react with AgNO₃ to form AgCl.

4. **Conclusion**:
- Since CCl₄ does not contain any ions that can react with AgNO₃, it will not give a white precipitate. Therefore, the correct answer is CCl₄.

### Final Answer:
- The compound that will not give a white precipitate when AgNO₃ is added to its solution is CCl₄.
