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.

Chemists from the National University of Singapore (NUS) have developed a straightforward method to convert common chemicals like carboxylic acids, alcohols, and alkanes directly into valuable alkenes ...

In this article we are going to share the various methods to prepare the alkene and specially the ozonolysis of alkenes to know the number and position of double bond present in the alkene compounds.

Installing directing groups, tiny signposts that tell a functional group where to attach to a molecule, is time consuming, but usually necessary. Ming Joo Koh and colleagues at the National University ...

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 ...
