Ethylene to formaldehyde

Explanation

To convert ethylene (C2H4) to formaldehyde (HCHO), we can use the ozonolysis reaction. Here’s a step-by-step breakdown of the process:

### Step 1: Identify the Reactants and Products
- **Reactant**: Ethylene (C2H4) - which has the structure CH2=CH2.
- **Product**: Formaldehyde (HCHO) - which has the structure H2C=O.

### Step 2: Perform Ozonolysis
- **Reaction**: Ethylene undergoes ozonolysis. We introduce ozone (O3) to the double bond of ethylene.
