Ethene, also known as ethylene, is a colorless gas that is the simplest alkene, consisting of two carbon atoms and four hydrogen atoms (C2H4). It is a key building block in the production of various chemicals and plastics, including polyethylene, which is widely used in packaging materials. Ethene is naturally produced by plants and fruits, playing a crucial role in the ripening process. It acts as a plant hormone, influencing growth and development. Additionally, ethene is used in agriculture to accelerate the ripening of fruits and in the chemical industry for synthesizing other organic compounds.
