The rapid disappearance of the amber color of the bromine at room temperature is characteristic of reaction with alkenes. (colorless) (purple) (colorless) (brown ppt.) Reaction of an alkene with ...

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 ...

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.

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 ...

The researchers used an easily accessible and reusable chemical called vinyl ketone as the "olefination reagent" to help ...

Ozone pollution, typically associated with warm weather and strong sunlight, has begun to manifest alarmingly in winter. This ...

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 ...

the study identified alkene ozonolysis as the dominant driver of O₃ formation, rather than the traditional radical sources initiated by photolysis. This chemical reaction occurs without sunlight ...
