Researchers synthesized weird molecules that exist in three dimensions, breaking Bredt's rule and helping to develop future ...

Chemical groups containing oxygen, nitrogen, silicon, and other heteroatoms often react during alkene coupling reactions, generating undesirable product mixtures. But a new, iron-catalyzed radical ...

Cubene and quadricyclene are descended from cubane and quadricylane, both cage-shaped structures with bonds that are fairly ...

Asymmetric ring‐opening reactions of bicyclic alkenes have emerged as a transformative approach in modern synthetic chemistry. These reactions capitalise on the inherent ring strain of fused cyclic ...

Chemists at UCLA are showing that some of organic chemistry’s most famous “rules” aren’t as unbreakable as once thought. By ...

Organic chemistry is packed with rules about structure and reactivity, especially when it comes to making and breaking ...

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.

The second homologous series is the alkenes. Their names all end in –ene, for example ethene. Alkenes all contain a carbon to carbon double bond which makes them more reactive than the alkanes. The ...
