Ethoxyethane does not react with

Options

A. HI
B. Conc. `H_(2)SO_(4)`
C. Na
D. `PCl_(5)`

Answer

To solve the question "Ethoxyethane does not react with", we will analyze the options given and determine which one does not lead to a reaction with ethoxyethane (C2H5OC2H5).

### Step-by-Step Solution:

1. **Identify Ethoxyethane**:
- Ethoxyethane is an ether with the structure C2H5OC2H5. It consists of two ethyl groups (C2H5) connected by an oxygen atom.

2. **Analyze the Reactivity of Ethoxyethane**:
- Ethers generally have low reactivity compared to other organic compounds. However, they can react under certain conditions.

3. **Evaluate Each Option**:
- **Option A: HI (Hydroiodic Acid)**
- Ethers can react with HI to form alcohols and alkyl iodides. Therefore, ethoxyethane can react with HI.

- **Option B: Concentrated H2SO4 (Sulfuric Acid)**
- Ethers can react with concentrated sulfuric acid, leading to cleavage of the ether bond. Thus, ethoxyethane can react with concentrated H2SO4.

- **Option C: Sodium (Na)**
- Sodium does not react with ethers because ethers do not have acidic protons and do not contain ionic functional groups. Sodium typically reacts with ionic species, and since ethoxyethane lacks these characteristics, it does not react with sodium.

- **Option D: PCl5 (Phosphorus Pentachloride)**
- Ethers can react with PCl5 to form alkyl chlorides and phosphoric acid. Therefore, ethoxyethane can react with PCl5.

4. **Conclusion**:
- Based on the analysis, the correct answer is **Option C: Sodium (Na)**, as ethoxyethane does not react with sodium.

### Final Answer:
Ethoxyethane does not react with **C. Sodium (Na)**.
