Ethylene on reaction with ozone gives

When ethylene reacts with ozone, it forms a cyclic intermediate called molozonide. This intermediate can then decompose into several products depending on the reaction conditions. The possible products include:

1. Formaldehyde (HCHO) and carbon dioxide (CO₂)
2. Carbon monoxide (CO) and formic acid (HCOOH)
3. Methanal (CH₂O) and hydrogen peroxide (H₂O₂)
4. Glyoxal (OHCCHO) and hydrogen peroxide (H₂O₂)

The most common products are formaldehyde and carbon dioxide, but the exact products formed depend on the reaction conditions and the concentrations of the reactants.
