Alkenes are generally colorless non-polar compounds, somewhat similar to alkanes but more reactive. The first few members of the series are gases or liquids at room temperature. The simplest alkene, ethylene (C2H4) (or "ethene" in the IUPAC nomenclature) is the organic compound produced on the largest scale industrially. [5]

Alkenen of olefinen zijn onverzadigde koolwaterstoffen waarin minstens één paar koolstofatomen verbonden is door een dubbele binding. Alkenen met één zo'n dubbele binding en geen andere functionele groepen hebben de algemene verhoudingsformule . De eenvoudigste lineaire alkenen zijn: Vanaf buteen zijn er structuurisomeren mogelijk.

To name alkenes given formulas and write formulas for alkenes given names. As noted before, alkenes are hydrocarbons with carbon-to-carbon double bonds (R 2 C=CR 2) and alkynes are hydrocarbons with carbon-to-carbon triple bonds (R–C≡C–R).

2024年4月15日 · 在有机化学的世界里，alkenes和Olefins这两个术语常常被混用，然而它们其实蕴含着独特的含义。 alkenes，如同其名，专指那些只含有一条碳碳双键的饱和链烃，是烯烃大家族中的基础成员（双键的唯一性是它们的标志） [16]。 而Olefins的概念更为广泛，它不仅包括alkenes，还包括了拥有一个或多个双键的环状和非环状碳氢化合物，比如环烯烃（cycloalkenes）和多烯烃（含有多个双键的化合物） [17]。 当alkenes的双键数量超过一 …

Alkenes are the raw materials for plastics such as polyethene, PVC, polypropylene, and polystyrene, among others. The chemistry of alkenes is present in unsaturated fats, beta-carotene, and light through vision. What are the characteristics of alkenes?

2022年12月1日 · Alkenes are hydrocarbons that contain a carbon-carbon double bond (=C=C=) in their molecule. Alkenes are commonly known as olefins (in Latin, olefins mean “oil-forming) because the lower member of the series reacts with chlorine to form oily products. Ethylene (C 2 H 4) is the first member of the series.

2022年4月22日 · Alkenes are unsaturated hydrocarbons containing carbon-carbon double bonds. The carbon-carbon double bond is the functional group for alkenes, known as ethylenic linkage. The general formula of an alkene is C n H 2n, where n is the integer number. Alkenes consist of two atoms of hydrogen less than the alkanes.

alkene单指只含一组 碳氢双键 的集合，olefin是个很广义的概念. 比如这篇文献摘要中的划线句中同时出现了olefin和alkene，那么它们有什么不同呢？ 为什么分别要用两个单词…
