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.

For example, ethene reacts with water (in the presence of heat and a catalyst) to produce the alcohol ethanol. Addition polymerisation uses addition reactions to turn alkenes into polymers.

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 ...

Reaction with Sodium Reacts to form ... a double bond or a triple bond), but saturated hydrocarbons (alkanes) do not decolourise bromine water. The bromine water test is performed to differentiate ...

"It would be better to directly use dinitrogen and alkenes to synthesize alkyl amines under mild conditions," he adds. "But ...

Students will be able to explain that the color that a substance turns a pH indicator is a characteristic property of that substance. Students will also be able to explain that different substances ...

Video recorded by mom Kaleigh Butler shows the infant's over-the-top reaction as she takes a first nibble — followed by a giant chomp.

Trisubstituted alkenes are major constituents of biologically active molecules and serve as key substrates for a broad range of stereospecific reactions that form sp 3-hybridized scaffolds.

Sarah Vine and Andrew Pierce bring their own no-holds-barred opinions, insights and reaction (clue is in the title) to the biggest stories of the week. New episodes every Wednesday, wherever you ...
