"Ethylin" Natural Recordings by Native Speakers

Ethylenes are a class of organic compounds that contain a carbon-carbon double bond (CC) and are derived from ethylene (C2H4). They are also known as unsaturated hydrocarbons. Ethylenes are typically colorless, volatile liquids or gases with a characteristic odor. They are widely used in various industries such as petroleum refining, plastics manufacturing, and agricultural production. Specific examples of ethylenes include ethylene itself, propylene, butylene, and pentene.
