C2H4

C₂H₄ is the chemical formula for ethylene, also known as ethene. It is a simple alkene and consists of two carbon atoms and four hydrogen atoms. Ethylene is a colorless gas at room temperature and standard pressure and is one of the most important feedstocks in the chemical industry, primarily used in the production of plastics, antifreeze, and various synthetic materials. Here are some key properties and information about ethylene: 1. **Molecular Structure**: Ethylene has a double bond between the two carbon atoms, which gives it its alkene classification. The structure can be represented as H₂C=CH₂. 2. **Physical Properties**: - Boiling Point: -103.7 °C - Melting Point: -169.4 °C - Solubility: Ethylene is slightly soluble in water but more soluble in organic solvents. 3. **Uses**: - Production of polyethylene, a widely used plastic. - Manufacturing of various chemicals, such as ethanol and ethylene oxide. - It is also used in agriculture as a plant hormone to stimulate ripening in fruits. 4. **Reactivity**: Ethylene is reactive due to the presence of the double bond and can undergo various chemical reactions, such as addition reactions with halogens, hydrogenation, and polymerization.
