Which of the following compounds will give curdy precipate with `AgNO_(3)` solution?

Options

A.
B.
C.
D.

Explanation

To determine which of the given compounds will give a curdy precipitate with AgNO₃ solution, we need to identify which compound can easily release chloride ions (Cl⁻). The chloride ions react with silver nitrate (AgNO₃) to form a white precipitate of silver chloride (AgCl).

### Step-by-Step Solution:

1. **Understanding the Reaction**:
- Silver nitrate (AgNO₃) reacts with chloride ions to form silver chloride (AgCl), which is a white curdy precipitate.
- The key to this question is identifying which compound can release chloride ions.

2. **Analyzing Each Compound**:
- **Compound A**: This is an aryl halide. In aryl halides, the carbon-chlorine bond has partial double bond character due to resonance. This means that the chlorine is not easily released as a chloride ion. Therefore, it will not give a curdy precipitate with AgNO₃.

- **Compound B**: This compound forms a vinylic carbocation upon the removal of chloride. Vinylic carbocations are unstable due to the high s-character of the sp² hybridized carbon. Thus, this compound also does not easily release chloride ions and will not form a precipitate.

- **Compound C**: Similar to Compound B, this compound also forms a vinylic carbocation upon the removal of chloride. It shares the same instability issues and therefore will not release chloride ions easily.

- **Compound D**: This compound, when fluorine leaves, forms a stable carbocation due to its aromatic nature. Aromatic compounds are highly stable and can easily release chloride ions. The presence of aromaticity allows for the formation of a stable structure, making it likely to react with AgNO₃ and form a curdy precipitate of AgCl.

3. **Conclusion**:
- After analyzing all the compounds, we conclude that **Compound D** is the only compound that will give a curdy precipitate with AgNO₃ solution due to its ability to easily release chloride ions.

### Final Answer:
**Option D** will give a curdy precipitate with AgNO₃ solution.
