In organic chemistry, an alkene, or olefin, is a hydrocarbon containing a carbon–carbon double bond. [1] The double bond may be internal or in the terminal position. Terminal alkenes are also known as α-olefins .
28 kwi 2024 · Although there is only one alkene with the formula C 2 H 4 (ethene) and only one with the formula C 3 H 6 (propene), there are several alkenes with the formula C 4 H 8. Here are some basic rules for naming alkenes from the International Union of Pure and Applied Chemistry (IUPAC):
23 sty 2023 · Alkenes are a class of hydrocarbons that contain only carbon and hydrogens. They are unsaturated compounds that contain at least one carbon-to-carbon double bond. Another term that is often used to ….
13 sie 2022 · Perhaps the simplest addition reaction is hydrogenation—a reaction with hydrogen (H 2) in the presence of a catalyst such as nickel (Ni) or platinum (Pt). The product is an alkane having the same carbon skeleton as the alkene. Alkenes also readily undergo halogenation—the addition of halogens.
Alkenes are hydrocarbons (compounds consisting entirely of carbon and hydrogen) that contain a carbon-carbon double bond (C=C, where one bond is a sigma bond, and the other a pi bond). The carbon-carbon double bond is the functional group of an alkene. The general structure of an alkene. The structure of ethylene, the simplest alkene.
Core Chemistry 14 - 16. This page introduces alkenes - what they are, and their reactions with bromine, hydrogen and steam. It also introduces the important terms "unsaturated", "addition reaction" and "functional group".
25 mar 2023 · Alkenes are aliphatic hydrocarbons containing carbon-carbon double bonds and general formula C n H 2n. Naming Alkenes. [ | edit source] Alkenes are named as if they were alkanes, but the "-ane" suffix is changed to "-ene".
