In organic chemistry, an alkene, or olefin, is a hydrocarbon containing a carbon–carbon double bond. The double bond may be internal or in the terminal...

organic chemistry, terminal alkenes (alpha-olefins, α-olefins, or 1-alkenes) are a family of organic compounds which are alkenes (also known as olefins) with...

Pyramidal alkenes are alkenes in which the two carbon atoms making up the double bond are not coplanar with their four substituents. This deformation...

temperature. Thus, trans alkenes, which are less polar and more symmetrical, have lower boiling points and higher melting points, and cis alkenes, which are generally...

engines for their higher octane rating. Trans-alkenes are about 1 kcal/mol more stable than cis-alkenes. An example of this effect is cis- vs trans-2-butene...

molecules with multiple double bonds, it is sometimes necessary to indicate the alkene location for each E or Z symbol. For example, the chemical name of alitretinoin...

organic chemistry, enone–alkene cycloadditions are a version of the [2+2] cycloaddition. This reaction involves an enone and alkene as substrates. Although...

ketones, and carboxylic acids. The reaction is predominantly applied to alkenes, but alkynes and azo compounds are also susceptible to cleavage. The outcome...

In enzymology, an alkene monooxygenase (EC 1.14.13.69) is an enzyme that catalyzes the chemical reaction propene + NADH + H+ + O2 ⇌ {\displaystyle \rightleftharpoons...

reacts preferentially at the disubstituted alkene, whereas epoxidation with mCPBA occurs at the trisubstituted alkene. In another synthetic method Markovnikov...
