Ethylene is a colorless gas that is widely used in the chemical industry. It is the simplest alkene, consisting of two carbon atoms and four hydrogen atoms, with the chemical formula C2H4. Ethylene plays a crucial role in the production of various plastics, antifreeze, and synthetic fibers, making it an essential building block in many industrial processes. In addition to its industrial applications, ethylene is also a natural plant hormone that regulates growth and ripening. It influences processes such as fruit ripening and flower wilting, making it significant in agriculture and horticulture. Understanding ethylene's dual role in both chemistry and biology highlights its importance in our daily lives.
