Answer

To solve the question regarding the reaction of ethyl ethanoate with sodium in ethanol, we will break down the steps involved in identifying the type of reaction that occurs.

### Step-by-Step Solution:

1. **Identify the Reactants**: The reaction involves ethyl ethanoate (an ester) and sodium in the presence of ethanol. The chemical formula for ethyl ethanoate is CH₃COOC₂H₅.

2. **Understand the Reaction Conditions**: The presence of sodium (Na) and ethanol (C₂H₅OH) indicates that this is a reduction reaction. Sodium acts as a reducing agent, and ethanol serves as a solvent.

3. **Analyze the Products**: The products of the reaction are two molecules of ethyl alcohol (C₂H₅OH). This suggests that the ester is being reduced to alcohol.

4. **Determine the Type of Reaction**: The specific type of reduction occurring here is known as the Bouin-Blanc reduction. This reaction is characterized by the reduction of carbonyl compounds (like esters) to alcohols using sodium and ethanol.

5. **Conclude the Reaction Type**: Therefore, the reaction can be classified as a Bouin-Blanc reduction, which is a named reaction in organic chemistry.

### Final Answer:
The reaction `CH₃COOC₂H₅ + Na + C₂H₅OH → 2 C₂H₅OH` is called a **Bouin-Blanc reduction**.
