The bromination reactions and mechanisms are compared ... The rapid disappearance of the amber color of the bromine at room temperature is characteristic of reaction with alkenes. (colorless) (purple) ...

This causes a smoky flame. Alkenes have a functional group C=C – the part of the molecule that takes part in reactions. Alkanes, in contrast, do not have a functional group and are less reactive ...

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 ...

Asymmetric ring-opening reactions of bicyclic alkenes are a significant area of research in organic chemistry, particularly for their ability to produce valuable chiral compounds. These reactions ...

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.

Alkenes play a crucial role in producing everyday ... Their new method combines two known chemical reactions—photocatalytic ...
