Definition

Noun: 1. Any unsaturated aliphatic hydrocarbon: A chemical compound belonging to a series of hydrocarbons characterized by having one or more carbon-carbon double bonds in their molecular structure. The term is synonymous with "alkene."

Usage and Examples

The word olefine is a technical term used primarily in the field of chemistry. * Ethylene is the simplest olefine. * Many plastics are manufactured from olefines like propylene. * The chemical reactivity of an olefine is centered on its carbon-carbon double bond.

Advanced Usage

• The term olefine is considered somewhat dated in modern systematic chemistry, where alkene is the preferred IUPAC name. However, it remains in common use in industrial and petrochemical contexts (e.g., "olefin plant").
• It can be used attributively as a noun modifier, as in olefine chemistry or olefine production.

Variants and Related Words

• Alkene (n): The modern, systematic synonym for olefine.
• Olefin (n): An alternative, and now more common, spelling of .
• Polyolefin (n): A polymer derived from simple olefines (e.g., polyethylene, polypropylene).
