B. `(CH_(3))_(3)CCl overset(C_(2)H_(5)Cl)to`
C. `RCOOK overset("Electrolysis")underset("Oxidation")to`
D. `RCOOAg overset(I_(2))underset(hv)to`

Answer

To determine which of the given reactions would yield a good hydrocarbon product, we need to analyze each reaction step by step.

### Step-by-Step Solution:

1. **Identify the Reactions**:
We have four reactions to consider. Let's denote them as Reaction A, Reaction B, Reaction C, and Reaction D.

2. **Analyze Reaction A**:
- Reaction: CH3-CH3 + Cl2 (with hν)
- This is a free radical halogenation reaction.
- The product formed will be CH3-CH2-Cl (monochlorination).
- This reaction does not produce a hydrocarbon; it produces a haloalkane.

3. **Analyze Reaction B**:
- Reaction: (CH3)3CCl + C2H5Cl
- This is a tertiary alkyl halide reacting with another alkyl halide.
- No significant reaction will occur here because tertiary halides are relatively stable and do not react further in this context.
- Therefore, this reaction does not yield a hydrocarbon.

4. **Analyze Reaction C**:
- Reaction: Electrolysis of RCOOK (Kolbe Electrolytic Reaction)
- This reaction involves the electrolysis of a potassium salt of a carboxylic acid.
- During electrolysis, CO2 is eliminated, and hydrocarbons (RR) are formed.
- This reaction is known to produce hydrocarbons effectively, making it a good candidate.

5. **Analyze Reaction D**:
- Reaction: R-C≡C-Ag + I2 (with hν)
- This reaction involves the formation of R-C(=O)-O-R and the release of CO2.
- No hydrocarbon is formed in this reaction, as the products do not include hydrocarbons.

6. **Conclusion**:
- Among the reactions analyzed, only Reaction C (Kolbe Electrolytic Reaction) produces a hydrocarbon product effectively.
- Therefore, the answer is **Reaction C**.
