Webdiscuss the uses and sources of alkenes including catalytic cracking Uses of ethene and propene Produced from ethylene (ethene) Produced from propylene (propene) Catalytic Cracking to Form Ethylene Cracking is the name given to breaking up large hydrocarbon molecules into smaller and more useful bits. WebThe double C=C bond is what makes alkenes reactive. It can break open and new atoms can be added across it. Alkenes are not always small molecules. How do you test for an alkene? Alkenes turn bromine water from orange to colourless. Universal indicator turns purple in the presence of an alkali.

WebAlkenes can take part in reactions that alkanes cannot. For example, ethene molecules can react together to form poly(ethene), a polymer. Alkenes will react with bromine water and turn it... WebAlkanes and alkenes both undergo complete combustion, but only alkenes can undergo addition reactions. Complete combustion The complete combustion of alkanes and … WebAlkane does not have a reaction with the bromine water since it is way less reactive than alkene, alkane only has a carbon-carbon bond compared to alkene having carbon-carbon double bond. Alkene or alkyne react to bromine water when the double bond is broken, a bromine atom is attached to each carbon. rami mundijeux akamon gratuit
