Name the two processes used to produce ethene from crude oil.
The salt solution is electrolysed with a carbon anode (positive electrode). Write the equation for the reaction at the anode.
Draw the structure, with every atom and bond shown, of dichloroethane.
When dichloroethane, $\text{C}_2\text{H}_4\text{Cl}_2$, is strongly heated, chloroethene, $\text{C}_2\text{H}_3\text{Cl}$, is produced. Name the other product of this reaction.
The structure of chloroethene is given. Draw a section of the structure of poly(chloroethene).
A factory uses 2250 tonnes of chloroethene to produce poly(chloroethene). Deduce the greatest mass of poly(chloroethene) that could be produced.
The actual yield of poly(chloroethene) is 2175 tonnes. Calculate the percentage yield.
