By the end you’ll be able to

define alkenes as unsaturated hydrocarbons containing a carbon-carbon double bond and distinguish them from alkanes
represent ethene, propene and butene using molecular formulae, displayed formulae and simple structural formulae
describe and explain the reaction of alkenes with bromine water as a test for unsaturation, including the decolourisation of orange bromine water

write and interpret equations for addition reactions of alkenes with hydrogen, halogens and steam to form saturated products

describe addition polymerisation as the formation of very long molecular chains from many alkene monomers and explain that the double bond opens to form single bonds in the polymer chain

draw and interpret the repeating unit of an addition polymer from a given alkene monomer and identify the monomer from a simple polymer structure

evaluate advantages and disadvantages of addition polymers in terms of useful properties and issues linked to persistence in the environment
