Normal alkanes C n H 2n+2 are extended linear chain molecules that form ordered lamellar structures and crystals. When the size of the chains reaches n > 120, such ultra-long alkanes manifest chain ...

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 ...

Alkenes are incredibly common in the molecular world, so researchers constantly seek more ways to use them in chemical transformations. Now, two independent teams have uncovered new alkene reactivity ...

A new cobalt catalyst designed by Paul Chirik and coworkers at Princeton University gives chemists two mechanisms for the price of one. The team’s alkene hydrogenation reaction runs differently ...

(Nanowerk News) The role of surface modification of nanoparticle catalysts in alkyne hydrogenation reactions was systematically investigated by the Center for Nanoscale Materials' NanoBio Interfaces ...

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.

Hydrocarbons – because they contain hydrogen and carbon only. Unsaturated – because they contain at least one C=C. Each alkene containing one C=C has two fewer hydrogen atoms than the corresponding ...
