Dienes are the names given to compounds with
In organic chemistry a diene (diolefin (/daɪˈoʊləfɪn/ dy-OH-lə-fin) or alkadiene) is a covalent compound that contains two double bonds, usually among carbon atoms. They thus contain two alkene units, with the standard prefix di of systematic nomenclature. As a subunit of more complex molecules, dienes … See more Dienes can be divided into three classes, depending on the relative location of the double bonds: 1. Cumulated dienes have the double bonds sharing a common atom. The result is more specifically … See more Polymerization The most heavily practiced reaction of alkenes, dienes included, is polymerization. 1,3-Butadiene is a … See more On an industrial scale, butadiene is prepared by thermal cracking of butanes. In a similarly non-selective process, dicyclopentadiene is obtained from coal tars. In the laboratory, more directed and more delicate processes … See more Webnon-bonded. For a molecule or ion to exhibit resonance, the structure must include ______ bonds and/or ______ electrons. 1) sp-sp sigma bond of 1,3-butadiyne. 2) sp2-sp2 sigma bond of 1,3-butadiene. 3) sp3-sp2 sigma bond of propene. 4) sp3-sp3 sigma bond of ethane.
