Acetylene is obtained by the electrolysis of

Options

A. Sodium succinate
B. Potassium fumarate
C. Both (A) and (B)
D. None of these

Answer

To determine which compound can produce acetylene (C2H2) through electrolysis, we need to analyze the given options: sodium succinate, potassium fumarate, both A and B, and none of these.

### Step-by-Step Solution:

1. **Understanding Acetylene Formation**:
- Acetylene (C2H2) has a triple bond between the two carbon atoms. To form acetylene, we need a precursor that can undergo electrolysis to yield this structure.

2. **Analyzing Sodium Succinate**:
- Sodium succinate has the structure: HOOC-CH2-CH2-COOH.
- In this structure, the carbon atoms are connected by single bonds (C-C).
- During electrolysis, sodium succinate can only lead to the formation of ethylene (C2H4) because it cannot form a triple bond directly from single bonds.

3. **Analyzing Potassium Fumarate**:
- Potassium fumarate has the structure: HOOC-CH=CH-COOH.
- Here, there is a double bond between the two carbon atoms (C=C).
- During electrolysis, the double bond can be converted into a triple bond (C≡C) through a process known as coal-bay electrolysis, which involves the removal of carbon dioxide (CO2) from the molecule.

4. **Electrolysis Process**:
- In the case of potassium fumarate, when subjected to electrolysis, CO2 is eliminated, and acetylene (C2H2) is formed.
- The reaction can be summarized as:
- 2 HOOC-CH=CH-COOH → C2H2 + 2 CO2 + 2 KOH + H+.

5. **Conclusion**:
- Since sodium succinate does not yield acetylene but potassium fumarate does, the correct answer is that acetylene is obtained by the electrolysis of potassium fumarate.

### Final Answer:
The correct option is **Potassium Fumarate**.
