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.

A major advance in alkene oligomerization catalysis was Brookhart’s 1995 report of highly active group 10 metal diimine systems. In contrast to nickel and palladium catalysts, the corresponding ...

Using an advanced photochemical box model, the study identified alkene ozonolysis as the dominant driver of O₃ formation, rather than the traditional radical sources initiated by photolysis.

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 ...

Using a photochemical box model, the study found that alkene ozonolysis was the main contributor to O 3 formation, rather than the typical radical sources initiated by photolysis. This reaction ...
