A.
B.
C.
D.

Answer

To determine which of the given compounds will react readily with an aqueous solution of sodium carbonate (Na₂CO₃), we need to analyze the nature of the compounds and their ability to react with a base like Na₂CO₃. Sodium carbonate is a weak base and can react with acids or acidic compounds.

### Step-by-Step Solution:

1. **Identify the Compounds**: We need to identify the compounds given in the question. Let's denote them as A, B, C, and D for simplicity.

2. **Understand the Reactivity with Na₂CO₃**: Sodium carbonate can react with acids to form carbon dioxide gas (CO₂) and a salt. Therefore, we are looking for compounds that can donate protons (H⁺ ions) or are acidic in nature.

3. **Analyze Each Compound**:
- **Compound A**: Check if it can donate a proton. If it is an acid or can form an acid upon reaction, it will react with Na₂CO₃.
- **Compound B**: Similarly, analyze if it can donate a proton or is acidic.
- **Compound C**: Check for acidity or proton donation ability.
- **Compound D**: Evaluate if it can act as an acid.

4. **Determine Stability of the Resulting Species**: If a compound can lose a proton, the resulting anion must be stable. For example, if the resulting anion is anti-aromatic or unstable, the reaction is less likely to occur.

5. **Identify the Most Reactive Compound**: After analyzing the stability and acidity of each compound, identify which one reacts readily with Na₂CO₃. The compound that forms a stable anion and can easily donate a proton will be the most reactive.

6. **Conclusion**: Based on the analysis, select the compound that is most likely to react with the aqueous solution of Na₂CO₃.

### Final Answer:
The compound that reacts readily with aqueous Na₂CO₃ is **Compound C** (as per the analysis).
