Which of the following is not obtained when propyl chloride and methyl chloride react with sodium in dry ether?

Options

A. `C_(2)H_(6)`
B. `C_(4)H_(10)`
C. `C_(3)H_(8)`
D. `C_(6)H_(14)`

Explanation

To solve the question, "Which of the following is not obtained when propyl chloride and methyl chloride react with sodium in dry ether?", we will analyze the reactions that take place when these alkyl halides react with sodium.

### Step-by-Step Solution:

1. **Identify the Reactants**:
- We have two alkyl halides: Propyl Chloride (C3H7Cl) and Methyl Chloride (CH3Cl).

2. **Understand the Reaction Type**:
- The reaction between alkyl halides and sodium in dry ether is known as the Wurtz Reaction. In this reaction, sodium reacts with the halogen atoms (chlorine in this case) to form sodium halide and a new alkane.

3. **Write the Reaction for Propyl Chloride and Methyl Chloride**:
- When Propyl Chloride (C3H7Cl) and Methyl Chloride (CH3Cl) react with sodium, the reaction can be represented as:
\[ \text{C3H7Cl} + \text{CH3Cl} + 2 \text{Na} \rightarrow \text{C4H10} + 2 \text{NaCl} \]
- Here, Butane (C4H10) is formed.

4. **Consider Other Possible Reactions**:
- If two molecules of Propyl Chloride react, the reaction would be:
\[ 2 \text{C3H7Cl} + 2 \text{Na} \rightarrow \text{C6H14} + 2 \text{NaCl} \]
- This produces Hexane (C6H14).

5. **Consider the Reaction of Methyl Chloride with Itself**:
- If two molecules of Methyl Chloride react, the reaction would be:
\[ 2 \text{CH3Cl} + 2 \text{Na} \rightarrow \text{C2H6} + 2 \text{NaCl} \]
- This produces Ethane (C2H6).

6. **List the Products Obtained**:
- From the above reactions, we can summarize the products:
- Butane (C4H10)
- Hexane (C6H14)
- Ethane (C2H6)

7. **Identify the Missing Product**:
- The question asks which product is NOT formed. The options typically include:
- Butane (C4H10)
- Hexane (C6H14)
- Ethane (C2H6)
- Propane (C3H8)
- Among these, Propane (C3H8) is not formed in any of the reactions discussed.

### Conclusion:
The product that is NOT obtained when propyl chloride and methyl chloride react with sodium in dry ether is **Propane (C3H8)**.
