A chemical term for unsaturated hydrocarbons containing at least one carbon–carbon double bond. In Japanese, it is primarily expressed using the loanword オレフィン or the native term アルケン, with usage depending on context.
The learner wants to refer to the class of compounds known as olefins in chemistry.
The most common and direct equivalent, widely used in both academic and industrial contexts. It is a loanword from English.
この反応ではオレフィンが生成される。
Olefins are produced in this reaction.
The IUPAC-preferred term, commonly used in formal chemical nomenclature and textbooks. It is synonymous with olefin.
A more explicit term meaning 'olefinic hydrocarbon', used when clarity is needed in technical documents.
オレフィン系炭化水素は付加反応を起こしやすい。
Olefinic hydrocarbons readily undergo addition reactions.
Both terms refer to the same class of compounds. オレフィン is more common in industry and older literature, while アルケン is the systematic IUPAC name and is preferred in modern academic settings. In everyday chemical contexts, either is acceptable.
