In a development that could revise organic chemistry textbooks, a new catalytic version of alkene dichlorination makes the reaction more versatile. Now, researchers have devised the first catalytic ...

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.

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.

A dilute solution of bromine is added to samples of heptane and cyclohexene. The bromination reactions and mechanisms are compared. UV light splits the bromine molecule into two reactive radicals, ...
