Options

A.
B. `C_(6)H_(10)` (Cyclohexene)
C. `CH_(2)=CH_(2)`
D.

Answer

To determine in which cases the products of oxidative and reductive ozonolysis are different, we will analyze the ozonolysis of various compounds step by step.

### Step 1: Understand Ozonolysis
Ozonolysis is the oxidative cleavage of carbon-carbon double bonds (alkenes or alkynes) using ozone (O3). There are two types of ozonolysis:
- **Oxidative Ozonolysis**: Involves the use of oxidizing agents (like H2O2) and converts aldehydes into carboxylic acids.
- **Reductive Ozonolysis**: Involves reducing agents (like zinc dust) and typically stops at aldehydes and ketones without further oxidation.

### Step 2: Analyze Each Option

#### Option 1: C=C with R groups
1. **Oxidative Ozonolysis**: Cleavage of the double bond leads to the formation of a ketone and an aldehyde. The aldehyde is then oxidized to a carboxylic acid.
- Products: Ketone and Carboxylic Acid
2. **Reductive Ozonolysis**: Cleavage of the double bond leads to the formation of a ketone and an aldehyde, but no further oxidation occurs.
- Products: Ketone and Aldehyde
3. **Conclusion**: Different products in oxidative and reductive ozonolysis.

#### Option 2: Cyclohexene
1. **Oxidative Ozonolysis**: Cleavage leads to the formation of aldehydes, which are oxidized to carboxylic acids.
- Products: Carboxylic Acid
2. **Reductive Ozonolysis**: Cleavage leads to aldehydes, which do not undergo further oxidation.
- Products: Aldehyde
3. **Conclusion**: Different products in oxidative and reductive ozonolysis.

#### Option 3: Ethene
1. **Oxidative Ozonolysis**: Cleavage leads to the formation of formaldehyde, which is oxidized to carbon dioxide and water.
- Products: Carbon Dioxide and Water
2. **Reductive Ozonolysis**: Cleavage leads to formaldehyde, with no further oxidation.
- Products: Formaldehyde
3. **Conclusion**: Different products in oxidative and reductive ozonolysis.

#### Option 4: C=C with R, R', R'' groups
1. **Oxidative Ozonolysis**: Cleavage leads to the formation of ketones.
- Products: Ketone
2. **Reductive Ozonolysis**: Cleavage also leads to the formation of ketones.
- Products: Ketone
3. **Conclusion**: Same products in both oxidative and reductive ozonolysis.

### Final Conclusion:
- **Different Products**: Options 1, 2, and 3.
- **Same Products**: Option 4.

### Answer:
The products of oxidative and reductive ozonolysis are different in options 1, 2, and 3.
