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 ...

Organometallic alkane complexes are fascinating compounds that involve the bonding of alkanes, such as methane, to metal centers. These complexes play a crucial role in various chemical processes ...

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 ...

An unsolved challenge in catalysis is the efficient and selective functionalization of simple alkanes and plentiful hydrocarbon feedstocks. One promising approach since the late 1990’s is the use of ...

Ultimately, alkenes contributed to nearly 90% of the O₃ during the episodes. The research highlights key alkene species— trans / cis -2-butene and propene—as major contributors to 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 ...

In a recent study published in ACS Applied Materials & Interfaces on November 1, 2024, the team successfully developed a promising catalyst that could revolutionize the selective oxidation of alkanes.
