Ozonolysis of products obtained from alkene, 2-methyl-2-butene are

Options

A. `HCHO+HCHO`
B. `CH_(3)CHO+HCHO`
C. `CH_(3)CHO+CH_(3)COCH_(3)`
D. `HCHO+CH_(3)COCH_(3)`

Answer

To solve the problem of ozonolysis of 2-methyl-2-butene, we will follow these steps:

### Step 1: Identify the structure of 2-methyl-2-butene
2-methyl-2-butene is an alkene with the following structure:
- It has a double bond between the second and third carbon atoms.
- The structure can be represented as:

```
CH3
|
CH3-C=C-CH3
|
H
```

### Step 2: Perform ozonolysis
Ozonolysis involves the reaction of the alkene with ozone (O3) to form an ozonide. In the presence of a reducing agent like zinc (Zn), the ozonide will decompose into carbonyl compounds.

### Step 3: Draw the ozonide structure
When 2-methyl-2-butene reacts with ozone, it forms an ozonide. The ozonide structure can be represented as follows:

```
CH3
|
CH3-C-O-O-C-CH3
|
O
```

### Step 4: Breakdown of the ozonide
The ozonide undergoes cleavage in the presence of zinc and water, leading to the formation of carbonyl compounds. The cleavage will yield:

1. Acetone (CH3-CO-CH3)
2. Acetaldehyde (CH3-CHO)

### Step 5: Write the final products
The final products of the ozonolysis of 2-methyl-2-butene are:
- Acetone (CH3-CO-CH3)
- Acetaldehyde (CH3-CHO)

### Conclusion
The ozonolysis of 2-methyl-2-butene yields acetone and acetaldehyde.
