Options

A. Formation of a complex
B. Evolution of `Cl_(2)` gas
C. Chloride ion is not formed
D. `"AgNO"_(3)` does not give Ag ions

Answer

To solve the question of why CCl₄ does not give a precipitate with AgNO₃, we can break it down into a step-by-step explanation:

### Step 1: Understanding the Reaction
When CCl₄ (carbon tetrachloride) is mixed with AgNO₃ (silver nitrate), we are looking for the formation of a precipitate, specifically AgCl (silver chloride), which is known to be a white precipitate.

**Hint:** Consider what is required for a precipitate to form in a chemical reaction.

### Step 2: Analyzing CCl₄ Structure
CCl₄ is a covalent compound. It consists of one carbon atom bonded to four chlorine atoms through covalent bonds. In covalent bonding, atoms share electrons rather than transferring them completely.

**Hint:** Recall the nature of covalent bonds and how they differ from ionic bonds.

### Step 3: Valence Electrons in CCl₄
In CCl₄, the carbon atom has 4 valence electrons, and each chlorine atom has 7 valence electrons. The carbon shares one electron with each chlorine atom, resulting in a complete octet for carbon and each chlorine.

**Hint:** Think about how electron sharing affects the availability of ions in the solution.

### Step 4: Lack of Chloride Ion Formation
Since CCl₄ is covalently bonded, it does not dissociate into ions in solution. This means that no chloride ions (Cl⁻) are produced when CCl₄ is mixed with AgNO₃. The formation of AgCl requires the presence of Cl⁻ ions.

**Hint:** Consider what ions are necessary for the formation of a precipitate and whether they are present in the solution.

### Step 5: Conclusion
Since there are no chloride ions formed from CCl₄, there can be no reaction with AgNO₃ to produce AgCl. Therefore, no precipitate is formed.

**Final Answer:** CCl₄ does not give a precipitate with AgNO₃ because it does not produce chloride ions (Cl⁻) due to its covalent nature.

### Summary of the Reason
The reason CCl₄ does not give a precipitate with AgNO₃ is that no chloride ions are formed from CCl₄, which is necessary for the formation of AgCl precipitate.
