On heating calcium propionate, the product formed is

Options

A. 3-Pentanone
B. 2-Hexanone
C. 3-Methyl-2-butanone
D. Propanone

Answer

To solve the problem of what product is formed when heating calcium propionate, we can follow these steps:

### Step 1: Write the formula of calcium propionate.
Calcium propionate is a calcium salt of propanoic acid. Its chemical formula is:
\[ \text{Ca(C}_2\text{H}_5\text{COO)}_2 \]
This can also be represented as:
\[ \text{Ca(C}_3\text{H}_5\text{O}_2)_2 \]

### Step 2: Understand the reaction upon heating.
When calcium propionate is heated, it undergoes thermal decomposition. This process typically results in the formation of an alkane and calcium carbonate as a byproduct.

### Step 3: Write the decomposition reaction.
The thermal decomposition of calcium propionate can be represented as:
\[ \text{Ca(C}_2\text{H}_5\text{COO)}_2 \rightarrow \text{C}_3\text{H}_6\text{O} + \text{CaCO}_3 \]
Here, the main product formed is 3-pentanone (C₅H₁₀O) and calcium carbonate (CaCO₃) is formed as a side product.

### Step 4: Identify the product formed.
From the above reaction, we see that the main product formed is 3-pentanone.

### Step 5: Choose the correct option.
Among the options provided:
1. 3-pentanone
2. 2-hexanone
3. 3-methyl-2-butanone
4. Propanone

The correct answer is option 1: **3-pentanone**.

### Final Answer:
The product formed on heating calcium propionate is **3-pentanone**.
