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.

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 ...

The general formula of the alkanes is \({C_n}{H_{2n + 2}}\). They are insoluble in water. The names, molecular formula and the structural formula of the first eight alkanes must be learned.

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 ...
