Which of the following reaction is expected to readily give a hydrocarbon product in good yield ?

Options

A. `RCOOKunderset("Oxidation")overset("Electrolytic")to`
B. `RCOOAg overset(I_(2))to`
C. `CH_(3)CH_(3)overset(Cl_(2)//hv)to`
D. `(CH_(3))_(3)"CC"loverset(C_(2)H_(5)OH)to`

Answer

To determine which reaction is expected to readily give a hydrocarbon product in good yield, we will analyze each of the provided options step by step.

### Step 1: Analyze Option A
**Reaction:** Sodium carbonate reacting with electrolytic oxidation.

- In this reaction, we focus on the anode where oxidation occurs.
- The anion (R-C(=O)O⁻) will undergo oxidation, leading to the formation of R radicals and CO₂.
- The R radicals can combine to form a hydrocarbon (R-R), resulting in a hydrocarbon product.

**Conclusion for Option A:** This reaction can produce a hydrocarbon in good yield.

### Step 2: Analyze Option B
**Reaction:** An ester formation involving R-C(=O)O-Az reacting with I₂.

- The reaction with I₂ leads to the formation of R-C(=O)O radical and AzI.
- The subsequent steps involve the formation of radicals but ultimately lead to the formation of an ester, not a hydrocarbon.

**Conclusion for Option B:** This reaction produces an ester, not a hydrocarbon.

### Step 3: Analyze Option C
**Reaction:** Chlorination in the presence of light.

- In this reaction, chlorine replaces hydrogen atoms in the hydrocarbon chain through a free radical mechanism.
- The product will still contain chlorine and will not be a pure hydrocarbon.

**Conclusion for Option C:** This reaction does not produce a hydrocarbon.

### Step 4: Analyze Option D
**Reaction:** Reaction of CH₃CH₂Cl with ethanol (C₂H₅OH).

- In this reaction, the chlorine leaves to form a carbocation, which is then attacked by the ethanol.
- This leads to the formation of an ether, not a hydrocarbon.

**Conclusion for Option D:** This reaction produces an ether, not a hydrocarbon.

### Final Conclusion
After analyzing all the options, it is clear that **Option A** is the only reaction that readily gives a hydrocarbon product in good yield.
