Which product is obtained at the anode by the electrolysis of sodium butyrate -

Options

A. Butane + `CO_(2)`
B. Pentane + `CO_(2)`
C. Hexane + `CO_(2)`
D. Hexane

Answer

To determine the product obtained at the anode during the electrolysis of sodium butyrate, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Electrolysis**:
- Electrolysis is the process where an ionic substance is decomposed into simpler substances when an electric current is passed through it.

2. **Identifying Sodium Butyrate**:
- Sodium butyrate has the chemical formula C3H7COONa. It consists of the butyrate ion (C3H7COO-) and sodium ion (Na+).

3. **Electrolysis Reaction**:
- When sodium butyrate is subjected to electrolysis, it dissociates into its constituent ions: Na+ and C3H7COO-.

4. **Products of Electrolysis**:
- At the anode (positive electrode), oxidation occurs. The butyrate ion (C3H7COO-) can undergo oxidation.
- Oxidation of the butyrate ion leads to the formation of carbon dioxide (CO2) and other products.

5. **Formation of Hydrocarbons**:
- During the electrolysis, hydrocarbon products can also be formed. In this case, hexane (C6H14) is formed as a product.

6. **Final Products**:
- The products formed during the electrolysis of sodium butyrate include hexane (C6H14) and carbon dioxide (CO2).
- Specifically, at the anode, carbon dioxide (CO2) is released as a product of oxidation.

### Conclusion:
- The product obtained at the anode by the electrolysis of sodium butyrate is carbon dioxide (CO2).
