(CC BY-NC-ND) Alkenes, hydrocarbons containing carbon–carbon double bonds in addition to carbon-hydrogen bonds, are abundant in nature and readily available. They are commonly utilized for preparation ...

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.

Reaction of an alkene with aqueous potassium permanganate results in addition of two hydroxyl ... Add one or two drops of 1% bromine in dichloromethane to one sample of each hydrocarbon. Compare the ...

Complete combustion of alkenes produces carbon dioxide and water, provided there is a plentiful supply of oxygen. Incomplete combustion of alkenes occurs where oxygen is limited and produces water ...
