Options

B. `CH_(2) = CH - CH_(2)` - l
C. `CH_(2) = underset(I)underset(|)(C ) - CH_(3)`
D.

Answer

To determine which of the following compounds does not give a yellow precipitate with AgNO₃, we need to analyze the behavior of different types of haloalkanes when they react with silver nitrate. The yellow precipitate is primarily due to the formation of silver iodide (AgI).

### Step-by-Step Solution:

1. **Understanding the Reaction**:
The general reaction of haloalkanes (specifically iodides) with silver nitrate can be represented as:
\[ R-I + AgNO_3 \rightarrow R-ONO_2 + AgI \downarrow \]
Here, \(AgI\) is the yellow precipitate formed.

2. **Identifying the Types of Haloalkanes**:
We need to consider the types of haloalkanes given in the options. Alkyl iodides generally react to form yellow precipitate, while certain structures like vinyl iodides and phenyl iodides do not.

3. **Analyzing Each Option**:
- **Option 1: CH₃(CH₂)₃I (Alkyl Iodide)**: This is a primary alkyl iodide. It will react with AgNO₃ to form a yellow precipitate of AgI. Thus, this option does give a yellow precipitate.

- **Option 2: CH₂=CH-CH₂I (Allyl Iodide)**: This is an allyl iodide. It will also react with AgNO₃ to give a yellow precipitate of AgI. Thus, this option also gives a yellow precipitate.

- **Option 3: CH₂=CH-CH₂Cl (Vinyl Iodide)**: This compound has a strong C-I bond due to the conjugative effect. It does not readily react with AgNO₃ to form AgI, hence it does not give a yellow precipitate. This is the correct answer.

- **Option 4: CHI (Benzyl Iodide)**: This is a benzyl iodide. It will react with AgNO₃ to form a yellow precipitate of AgI. Thus, this option also gives a yellow precipitate.

4. **Conclusion**:
The compound that does not give a yellow precipitate with AgNO₃ is **Option 3: CH₂=CH-CH₂Cl (Vinyl Iodide)**.

### Final Answer:
**Option 3: CH₂=CH-CH₂Cl (Vinyl Iodide)** does not give a yellow precipitate with AgNO₃.
