Which of the following will not be formed when calcium formate is distilled with calcium acetate ?

Options

A. Propanone
B. Propanal
C. Ethanal
D. Methanal

Answer

To solve the question of which product will not be formed when calcium formate is distilled with calcium acetate, we can follow these steps:

### Step 1: Understand the Compounds
- **Calcium Formate (Ca(HCOO)2)**: It consists of two formate ions (HCOO^-) bonded to a calcium ion (Ca^2+).
- **Calcium Acetate (Ca(CH3COO)2)**: It consists of two acetate ions (CH3COO^-) bonded to a calcium ion (Ca^2+).

### Step 2: Identify the Distillation Process
- Distillation is a method used to separate components of a mixture based on their boiling points. In this case, we are looking at the products formed when these two compounds are heated together.

### Step 3: Determine Possible Reactions
1. **Calcium Formate Reaction**:
- When heated, calcium formate can decompose to produce methanol (HCHO) and calcium carbonate (CaCO3).
- Reaction:
\[ \text{Ca(HCOO)2} \rightarrow \text{HCHO} + \text{CaCO3} \]

2. **Calcium Acetate Reaction**:
- When heated, calcium acetate can decompose to produce propanone (acetone) and calcium carbonate.
- Reaction:
\[ \text{Ca(CH3COO)2} \rightarrow \text{CH3COCH3} + \text{CaCO3} \]

3. **Combined Reaction**:
- When both calcium formate and calcium acetate are heated together, they can react to form ethanol (C2H5OH) and calcium carbonate.
- Reaction:
\[ \text{Ca(HCOO)2} + \text{Ca(CH3COO)2} \rightarrow 2 \text{C2H5OH} + 2 \text{CaCO3} \]

### Step 4: Analyze the Products
- From the reactions above, the products formed are:
- Methanol (from calcium formate)
- Propanone (from calcium acetate)
- Ethanol (from the reaction of both)

### Step 5: Identify the Missing Product
- The question asks which product will **not** be formed.
- We have identified that methanol, propanone, and ethanol are formed. However, **propanol** is not mentioned as a product of any of the reactions.

### Conclusion
The product that will not be formed when calcium formate is distilled with calcium acetate is **propanol**.
