Selective hydrogenation of alkynes to alkenes occupies a central role in organic synthesis and industrial chemistry, enabling the conversion of triple bonds into double bonds with high precision. The ...

Alkenes are incredibly common in the molecular world, so researchers constantly seek more ways to use them in chemical transformations. Now, two independent teams have uncovered new alkene reactivity ...

A dilute solution of bromine is added to samples of heptane and cyclohexene. The bromination reactions and mechanisms are compared. UV light splits the bromine molecule into two reactive radicals, ...

In this article we are going to share the various methods to prepare the alkene and specially the ozonolysis of alkenes to know the number and position of double bond present in the alkene compounds.

Bromine water is an orange solution of bromine. It becomes colourless when it is shaken with an alkene. Alkenes can decolourise bromine water, but alkanes cannot. The slideshow shows this process.

The second homologous series is the alkenes. Their names all end in –ene, for example ethene. Alkenes all contain a carbon to carbon double bond which makes them more reactive than the alkanes. The ...
