One of the product formed in the electrolysis of sodium salt of succinic acid is

Options

A. Ethane
B. Butene
C. Ethylene
D. Acetylene

Answer

To solve the question regarding the product formed in the electrolysis of sodium salt of succinic acid, we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Compound**:
The sodium salt of succinic acid is known as sodium succinate, which has the formula \( \text{CH}_2\text{COONa} \).

2. **Understand the Electrolysis Process**:
During the electrolysis of sodium succinate, the process involves breaking down the sodium salt in an aqueous solution. This process is known as Kolbe electrolysis.

3. **Determine the Products**:
The electrolysis of sodium succinate leads to the formation of ethylene (ethene) as one of the primary products. The reaction can be summarized as:
\[ \text{CH}_2\text{COO}^- \rightarrow \text{CH}_2=\text{CH}_2 + 2 \text{CO}_2 + 2 \text{e}^- \]

4. **Identify the By-products**:
At the cathode, water is reduced to produce hydrogen gas:
\[ 2 \text{H}_2\text{O} + 2 \text{e}^- \rightarrow 2 \text{OH}^- + \text{H}_2 \]
Additionally, carbon dioxide is released during the process.

5. **Final Products**:
The final products of the electrolysis include:
- Ethylene (C2H4)
- Carbon dioxide (CO2)
- Hydrogen gas (H2)
- Sodium hydroxide (NaOH)

6. **Select the Correct Answer**:
From the options provided, ethylene (C2H4) is the correct product formed during the electrolysis of sodium succinate.

### Conclusion:
The product formed in the electrolysis of sodium salt of succinic acid is **ethylene (C2H4)**.
