Ethylene (C₂H₄) is the world's largest-volume petrochemical, produced over 200 million tonnes annually. As the simplest alkene with a reactive C=C double bond, it is the mother of polyethylene, PVC (via VCM), PET (via EG), and polystyrene (via SM). It is also a natural plant hormone that ripens fruits.
