3.8 describe the addition reaction of alkenes with bromine, including the decolourising of bromine water as a test for alkenes.

Alkenes undergo addition reactions with halogens. For example, a bromine molecule will add across the double bond of ethene to form 1,2-dibromoethane.


Since all alkenes contain a carbon- carbon double bond, they will all decolourise bromine. 

This reaction, therefore can be used to test for the presence of a carbon-carbon double bond.

Saturated compounds will not immediately decolourise bromine.

    Organic building blocks are mainly used for bottom-up modular assembly of metal-organic frameworks, organic molecular constructs, bromine series
