In organic chemistry a diene (/ ˈ d aɪ. iː n / DY-een) (diolefin (/ d aɪ ˈ oʊ l ə f ɪ n / 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. PU China 2019,2019.09.05-07 PU China 2019 Date: 05-07 SEP, 2019 Venue: Poly World Trade Center Exhibition Hall BOOTH NO.：620 In chemistry, a double bond is a covalent bond between two atoms involving four bonding electrons as opposed to two in a single bond. Double bonds occur most commonly between two carbon atoms, for example in alkenes. Many double bonds exist between two different elements: for example, in a carbonyl group Other articles where Double bond is discussed: covalent bond: …double lines (=) indicate a double bond between two atoms (i.e., involving two electron pairs), and triple lines (≡) represent a triple bond, as found, for example, in carbon monoxide (C≡O). Single bonds consist of one sigma (σ) bond, double bonds have one σ and one pi (π) bond, and… Ethene has a double bond between the two carbon atoms.

WHEN conjugated compounds exist, the delocalization is easier because the intermediate complexes formed are quite stable, and hence lower energy is required for the breaking of such pi-bonds.

It is important to explore the bonding in ethene in more detail because it has a direct impact on its chemistry. Unless you have some understanding of the true nature of the double bond, you can't really understand the way that ethene behaves. Double bonds are made of one pi bond and one sigma bond.

Double bonds occur most commonly between two carbon atoms, for example in alkenes .

The double bond lengths of a carbonyl group is about 1.2 angstroms and the strength is about 176-179 kcal/mol). It is possible to correlate the length of a carbonyl bond with its polarity; the longer the bond meaing the lower the polarity.

The term unsaturation mean a double bond or a ring system. For instance, in benzene there are 3 double bonds and 1 ring which gives us 4 DBE. Moreover a tripple bond can be regarded as DBE=2. The most common convention for depicting double bonds with unspecified configuration in molecules of all sizes uses a wavy bond. A crossed double bond has sometimes been used to indicate unspecified double bond configuration or a mixture of configurations. This type of bond is not considered acceptable for general use, although it may still be required by some computer software.
