  • Alkene - Wikipedia
    In organic chemistry, an alkene, or olefin, is a hydrocarbon containing a carbon–carbon double bond [1] The double bond may be internal or at the terminal position Terminal alkenes are also known as α-olefins
  • 13. 1: Alkenes- Structures and Names - Chemistry LibreTexts
    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):
  • Alkenes: formula, structure, nomenclature, properties, and uses
    What is an alkene? 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
  • Alkenes- Definition, Structure, Properties, Reactions, Uses
    Alkenes are unsaturated hydrocarbons containing carbon-carbon double bonds The general formula of an alkene is CnH2n
  • Alkenes: Structure and Stability - Chemistry Steps
    There are two factors to consider when deciding the more stable alkene One is the sterics which is expressed when comparing cis and trans isomers – trans alkenes are more stable because of a less steric hindrance: Sterics is the fancy word for the space available to atoms groups
  • What are Alkenes? - BYJUS
    An alkene whose double bond is at the end of the chain of carbon atoms is also sometimes called a terminal alkene Alkenes that have two, three and four alkyl groups bonded to the carbon atoms of the double bond are disubstituted, trisubstituted and tetrasubstituted respectively
  • Alkene Definition, Formula, Structure And Alkene Reactions
    One of the common synthesis of alkene is by the elimination reaction from alkyl halide, alcohol and similar compound Alkenes perform many addition reactions via the mechanism of electrophillic addition
  • Alkanes, Alkenes, and Alkynes Explained
    The most basic alkene is ethene (C₂H₄), which has two carbon atoms connected by a double bond and each carbon bonded to two hydrogens Alkenes can also be branched or have cyclic structures, such as in the case of cyclohexene (C₆H₁₀), which has a six-membered ring with one double bond
  • The Basics of General, Organic, and Biological Chemistry
    Briefly identify the important distinctions between an alkene and an alkane Classify each compound as saturated or unsaturated Identify each as an alkane, an alkene, or an alkyne
