A mixture of calcium acetate and calcium formate on heating gives

Options

A. HCHO
B. `CH_(3)CHO`
C. `CH_(3)COCH_(3)`
D. None

Answer

To solve the question regarding the products formed when a mixture of calcium acetate and calcium formate is heated, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Compounds**:
- The mixture consists of calcium acetate (Ca(CH3COO)2) and calcium formate (Ca(HCOO)2).

2. **Understand the Reaction**:
- When calcium salts of fatty acids are heated, they can undergo thermal decomposition. In this case, calcium acetate and calcium formate can decompose to form aldehydes and ketones.

3. **Write the Reaction**:
- The reaction can be represented as:
\[ \text{Ca(CH}_3\text{COO)}_2 + \text{Ca(HCOO)}_2 \xrightarrow{\text{heat}} \text{CH}_3\text{CHO} + \text{CaCO}_3 \]
- Here, CH3CHO represents acetaldehyde.

4. **Products Formation**:
- Upon heating, the calcium acetate decomposes to form acetaldehyde (CH3CHO) and calcium carbonate (CaCO3).
- The calcium formate also contributes to the formation of acetaldehyde.

5. **Final Products**:
- The final products of the reaction are acetaldehyde (CH3CHO) and calcium carbonate (CaCO3).

### Conclusion:
The mixture of calcium acetate and calcium formate upon heating gives acetaldehyde (CH3CHO) and calcium carbonate (CaCO3).
