Options

A. only one type of ketone
B. only one type of aldehyde
C. two types of ketone
D. two types of aldehyde

Explanation

To solve the problem of reductive ozonolysis of the compound `(CH₃)₂C=C(CH₃)₂` followed by hydrolysis, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Compound**:
The compound given is `(CH₃)₂C=C(CH₃)₂`, which is 2-butene (specifically, the isomer known as cis-2-butene).

**Hint**: Recognize the structure of the compound and identify the type of alkene.

2. **Ozonolysis Reaction**:
In ozonolysis, the double bond in the alkene is cleaved, and ozone adds to the double bond. This results in the formation of two carbonyl groups (C=O).

**Hint**: Remember that ozonolysis cleaves the double bond and forms carbonyl compounds.

3. **Draw the Ozonolysis Products**:
When the double bond in 2-butene is cleaved, we get two acetone molecules (C₃H₆O) as products. The structure can be represented as:
```
CH₃ O CH₃
\ // /
C==C
/ \
CH₃ CH₃
```
After ozonolysis, this will yield:
```
CH₃ O CH₃
\ //
C C
/ \
O O
```

**Hint**: Visualize the reaction and identify the resulting carbonyl compounds.

4. **Hydrolysis**:
The next step is hydrolysis, which involves the addition of water. However, in this case, since we already have carbonyl groups (from ozonolysis), hydrolysis does not change the products. The carbonyl groups remain as ketones.

**Hint**: Understand that hydrolysis typically converts ozonides into carbonyl compounds, but here, we already have them.

5. **Final Product**:
The final product after reductive ozonolysis followed by hydrolysis is acetone (C₃H₆O). Since both products from the ozonolysis are acetone, the final answer is simply acetone.

**Hint**: Confirm that the product is consistent with the expected outcome of the reaction.

### Conclusion:
The reductive ozonolysis of `(CH₃)₂C=C(CH₃)₂` followed by hydrolysis gives acetone as the final product.
