Options

A. `(CH_(3))_(2)CH-CH_(2)-CH(CH_(3))_(2)`
B. `(CH_(3))_(2)CH-CH_(2)-CH_(2)-CH(CH_(3))_(2)`
C. `CH_(3)-CH_(2)-C(CH_(3))_(2)CH_(2)-CH_(3)`
D. `(CH_(3))_(3)C-CH_(2)-CH_(2)-CH_(3)`

Explanation

To determine which alkane can be synthesized by the Wurtz reaction in good yield, we need to consider the nature of the Wurtz reaction and the symmetry of the alkanes involved.

### Step-by-Step Solution:

1. **Understand the Wurtz Reaction**:
The Wurtz reaction involves the coupling of two alkyl halides in the presence of sodium metal (Na) and an ether solvent. This reaction typically produces higher alkanes.

2. **Identify Symmetric Alkanes**:
For the Wurtz reaction to yield a good amount of product, the alkyl halides used should ideally be symmetric. This means that both alkyl halides should be the same or capable of forming the same alkane when they couple.

3. **Analyze the Given Options**:
Let's assume we have four options (A, B, C, D) for the alkanes. We need to evaluate each option to check if it is symmetric or not.

- **Option A**: Not symmetric.
- **Option B**: Symmetric.
- **Option C**: Not symmetric.
- **Option D**: Not symmetric.

4. **Select the Correct Option**:
Since only option B is symmetric, it is the alkane that can be synthesized by the Wurtz reaction in good yield.

### Conclusion:
The correct answer is **Option B**.
