Straightforward skeletal editing chemistry now enables the direct insertion of nitrogen into carbon–carbon double bonds.

two teams of chemists working independently have each come up with a new approach to filling the nitrogen-sized hole in the alkene cleavage toolbox. Both methods break carbon-carbon double bonds ...

DFT calculations as well as a current program of developing a wide range of alkylphosphine analogs indicate that lower alkene insertion barriers are due to a combination of high phosphine trans ...

The carbons of the alkene functional group, the site of unsaturation, are in the rounded rectangle. Since there is only one double bond, oleic acid is an example of a monounsaturated fatty acid.

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.

(colorless) (purple) (colorless) (brown ppt.) Reaction of an alkene with aqueous potassium permanganate results in addition of two hydroxyl groups to each side of the double bond to form a glycol. To ...

The table shows the first four alkenes, their molecular formulae, displayed formulae, structural formulae as well as a drawing of their ball-and-stick constructional models.
