Kolbe's electrolytic method can be applied on

Options

A. `CH_(3)COONa`
B. `(KOOC-CH_(2)-CH_2-COOK)`
C. `underset(KOOC-CH=HC-COOK)`
D. All of these

Answer

To determine which compounds Kolbe's electrolytic method can be applied to, we need to understand the method itself and analyze each option provided.

### Step-by-Step Solution:

1. **Understanding Kolbe's Electrolytic Method**:
- Kolbe's electrolytic method is used to prepare saturated hydrocarbons from substituted carboxylic acids through electrolysis.
- The process involves the decarboxylation (loss of CO2) and dimerization (combination of two radicals) of carboxylic acids.

2. **Analyzing the Options**:
- The options given are:
- (A) CH3COONa (Sodium acetate)
- (B) CH2=CHCOOK (Potassium acrylate)
- (C) CH≡C-COOK (Potassium propyne)
- (D) All of these

3. **Option A: CH3COONa**:
- Sodium acetate can undergo Kolbe's method.
- Upon electrolysis, it will form CH3 radicals after decarboxylation and subsequently dimerize to form ethane (C2H6).
- Therefore, Kolbe's method can be applied to CH3COONa.

4. **Option B: CH2=CHCOOK**:
- Potassium acrylate can also undergo Kolbe's method.
- After electrolysis, it will form radicals that can combine to form ethylene (C2H4) or other hydrocarbons.
- Thus, Kolbe's method can be applied to CH2=CHCOOK.

5. **Option C: CH≡C-COOK**:
- Potassium propyne can undergo Kolbe's method as well.
- The process will yield radicals that can combine to form hydrocarbons, specifically ethyne (C2H2).
- Hence, Kolbe's method can be applied to CH≡C-COOK.

6. **Conclusion**:
- Since Kolbe's electrolytic method can be applied to all the compounds listed (A, B, and C), the correct answer is:
- **All of these**.

### Final Answer:
Kolbe's electrolytic method can be applied on **all of these compounds**.
