What are the products obtained upon the ozonolysis of `2-`Methyl propene ?

Answer

To determine the products obtained from the ozonolysis of 2-methylpropene, we can follow these steps:

### Step 1: Identify the structure of 2-methylpropene
2-methylpropene is an alkene with the following structure:
\[ \text{CH}_3-\text{C}(\text{CH}_3)=\text{CH}_2 \]
This can also be represented as:
\[ \text{(CH}_3)_2\text{C}=\text{CH}_2 \]

### Step 2: Understand the ozonolysis process
Ozonolysis is a reaction where ozone (O₃) reacts with alkenes to cleave the double bond, forming ozonides as intermediates. The ozonides can then be further reduced to yield carbonyl compounds (aldehydes or ketones).

### Step 3: Draw the ozonide intermediate
When 2-methylpropene undergoes ozonolysis, it forms an ozonide. The ozonide structure for 2-methylpropene can be represented as:
\[ \text{CH}_3-\text{C}(\text{O})-\text{CH}_2-\text{O}-\text{C}(\text{O})-\text{CH}_3 \]

### Step 4: Perform reductive cleavage
In the presence of a reducing agent (like zinc in acetic acid), the ozonide undergoes reductive cleavage. This will yield:
- One molecule of propanone (also known as acetone), which has the structure:
\[ \text{CH}_3-\text{C}(\text{O})-\text{CH}_3 \]
- One molecule of formaldehyde (HCHO).

### Step 5: Write the final products
Thus, the products obtained from the ozonolysis of 2-methylpropene are:
1. Propanone (acetone)
2. Formaldehyde

### Final Answer
The products obtained upon the ozonolysis of 2-methylpropene are propanone (acetone) and formaldehyde.
