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.

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 ...

This reaction proceeds at room temperature and does not require sunlight or UV radiation to initiate it. The rapid disappearance of the amber color of the bromine at room temperature is characteristic ...

In a recent study in Green Chemistry, scientists from the King's College London and Brazilian Biorenewables National ...

Mark Gandelman. Called triazenolysis, the new process converts alkenes—common organic compounds such as petroleum—into multifunctional amines useful in various research and industrial ...

Published in Green Chemistry, researchers from King's College London and the Brazilian Biorenewables National Laboratory used enzymes to break down fatty acids in cooking oil into alkenes ...

The major breakthrough came thanks to a new method using enzymes to break down fatty acids in cooking oil into alkenes - the building block of fuels like petrol and diesel. Researchers at King’s ...
