C2H4

C₂H₄ is the chemical formula for ethylene, also known as ethene. It is a colorless gas with a sweet odor and taste and is the simplest alkene (a hydrocarbon that contains a carbon-carbon double bond). Here are some key points about C₂H₄: 1. **Structure**: Ethylene has a double bond between the two carbon atoms, leading to the molecular structure H₂C=CH₂. 2. **Uses**: Ethylene is an important compound in the chemical industry. It is primarily used in the production of polyethylene, one of the most common plastics. Additionally, it serves as a plant hormone that regulates various aspects of plant growth, including the ripening of fruits. 3. **Physical Properties**: Ethylene is a gas at room temperature and pressure. It is less dense than air and is flammable. 4. **Reactivity**: The presence of the double bond in ethylene makes it more reactive than alkanes. It can participate in various chemical reactions, including polymerization, combustion, and reactions with halogens. 5. **Safety**: Ethylene is considered hazardous due to its flammability and potential health effects if inhaled in large amounts.
