Alkene - Wikipedia
WebIn 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 . The International Union of Pure and Applied Chemistry (IUPAC) recommends using the name "alkene" only for acyclic hydrocarbons ...

7.1: Introduction to Alkenes - Chemistry LibreTexts
WebAlkenes are a class of hydrocarbons (i.e., containing only carbon and hydrogen). They are unsaturated compounds with at least one carbon-to-carbon double bond. The double bond makes alkenes more reactive than alkanes. Olefin is another term used to describe alkenes.

Alkenes and alkynes | Organic chemistry | Science | Khan Academy
WebAlkenes and alkynes can be transformed into almost any other functional group you can name! We will review their nomenclature, and also learn about the vast possibility of reactions using alkenes and alkynes as starting materials.

WebEach hydrogen is connected by a sigma bond, and only a sigma bond. they can rotate about the axis of this bond, but nothing more. The C=C does NOT have free rotation, so the molecule is locked into its planar geometry. the Hydrogen molecules are free to spin, but they can not move their position around the molecule.
Alkenes: General Formula, Structures, and Physical Properties - JoVE
WebThe general chemical formula of an alkene is CnH2n.Doubly bonded carbons are sp2 hybridized and have a trigonal planar geometry. The double bond is composed of a σ bond formed by the overlap of hybrid orbitals and a π bond produced by the lateral overlap of unhybridized 2p orbitals on both the carbons.
Alkanes, Alkenes, Alkynes | Brilliant Math & Science Wiki
WebA large and structurally simple class of hydrocarbons includes those substances in which all the carbon-carbon bonds are single bonds. These are called saturated hydrocarbons or alkanes. The simplest alkanes are methane (\ce {CH_4}), (CHX 4), ethane (\ce {C_2H_6}), (CX 2HX 6), and propane (\ce {C_3H_8}). (CX 3HX 8).
