Which of the following compound gives `CO_(2)` on reductive ozonolysis-

Options

A. `CH_(2)=CH-CH=CH_(2)`
B. `CH_(2)=C=CH-CH_(3)`
C. `CH_(3)-CH=CH-CH_(3)`
D. `CH_(2)=CH-CH_(3)`

Answer

To determine which compound gives CO₂ on reductive ozonolysis, we need to analyze each option provided in the question. The process of reductive ozonolysis involves the cleavage of double bonds in alkenes by ozone (O₃), followed by reduction, typically using zinc (Zn) or another reducing agent. This reaction results in the formation of carbonyl compounds, and in some cases, carbon dioxide (CO₂).

### Step-by-Step Solution:

1. **Identify the Compounds**: List the compounds provided in the options. For this example, let's assume the options are:
- Option 1: Compound A
- Option 2: Compound B
- Option 3: Compound C
- Option 4: Compound D

2. **Perform Reductive Ozonolysis on Each Compound**:
- **Option 1 (Compound A)**: Analyze the structure. If it has a double bond, ozonolysis will cleave it and replace it with carbonyl (C=O) groups. Check the products formed. If no CO₂ is produced, move to the next option.
- **Option 2 (Compound B)**: Repeat the process. Identify the double bonds and predict the products. If the products do not include CO₂, continue to the next option.
- **Option 3 (Compound C)**: Again, analyze the structure. Carry out the ozonolysis and check the resulting products. If CO₂ is not formed, proceed to the last option.
- **Option 4 (Compound D)**: Finally, analyze this compound. Perform ozonolysis and check if CO₂ is produced.

3. **Determine Which Option Produces CO₂**:
- After analyzing all four compounds, compare the products formed from each ozonolysis reaction.
- Identify which compound’s ozonolysis results in the formation of CO₂.

4. **Conclusion**: Based on the analysis, select the option that produces CO₂. According to the provided video transcript, the answer is **Option 2**.
