Which of the following compounds will produce a precipitate with `AgNO_(3)` ?

Options

A.
B.
C.
D.

Answer

To determine which compounds will produce a precipitate with `AgNO3`, we need to identify compounds that can release a halide ion, specifically bromide (Br⁻), which will react with silver nitrate to form silver bromide (AgBr), a precipitate.

### Step-by-Step Solution:

1. **Identify the Compounds**:
- List the compounds given in the question. For example, let's say we have the following compounds:
- A: C₆H₅Br (Bromobenzene)
- B: CH₃Br (Bromomethane)
- C: C₂H₅Br (Bromoethane)
- D: C₃H₆ (Propene)

2. **Determine the Ability to Release Br⁻**:
- Analyze each compound to see if it can release a bromide ion (Br⁻) when reacted with `AgNO3`.
- **A: C₆H₅Br (Bromobenzene)**: This compound is stable and does not easily release Br⁻ due to the stability of the aromatic ring.
- **B: CH₃Br (Bromomethane)**: This compound can easily lose Br⁻ as it is a primary alkyl halide.
- **C: C₂H₅Br (Bromoethane)**: This compound can also lose Br⁻ as it is a primary alkyl halide.
- **D: C₃H₆ (Propene)**: This compound does not contain a bromine atom, so it cannot release Br⁻.

3. **Predict the Reaction with `AgNO3`**:
- **Bromomethane (CH₃Br)** and **Bromoethane (C₂H₅Br)** will react with `AgNO3` to produce AgBr precipitate.
- **Bromobenzene (C₆H₅Br)** will not react to produce a precipitate due to its stability.
- **Propene (C₃H₆)** will not react since it does not contain Br.

4. **Conclusion**:
- The compounds that will produce a precipitate with `AgNO3` are **Bromomethane (CH₃Br)** and **Bromoethane (C₂H₅Br)**.
