WebAlkenes and Additional Polymerisation Alkenes. When a hydrocarbon is unsaturated, it has some double bonds. These are called an alkenes. Alkenes are more reactive than alkanes, since there is a ‘spare’ bond that could be made with another molecule. Naming alkenes. The same goes for __alkanes __(single bonds), except change the __-ene__ to ... Web8 de abr. de 2016 · Pressure and heat energy open the double bonds in the alkene and make it bond to form large polymer molecules. Alkenes are unsaturated hydrocarbons, meaning they don't have all the hydrogen that they could do, because of the double bond between some of the carbons. Under large amounts of energy - from heat and pressure …
WebSimply put, alkenes are molecules made up of just carbon and hydrogen atoms, with at least one C=C double bond. Alkenes are used to make polymers such as polystyrene … WebThe formation of polymers, long-chain molecules made of repeating units of monomers (the essential building blocks mentioned above), is a far more difficult experimental problem …
WebIn poly (alkenes) (such as poly (ethene)) and substituted poly (alkenes) (such as PVC) made of one type of monomer the repeating unit is the same as the monomer except that the C=C double bond is changed to a C-C single bond
