Question 1
2 marks · Hard
Answer and see the solution →State the names of the two functional groups present in the monomers that react together to form a polyester. For each group, state the name of the organic compound type it is found on (use "diol" or "dicarboxylic acid").
Question 2
5 marks · Hard
Answer and see the solution →The polymerisation of propane-1,3-diol and benzene-1,4-dicarboxylic acid forms a polyester. Propane-1,3-diol has the formula and benzene-1,4-dicarboxylic acid has the formula .
(a)[2 marks]Draw the structural formula of both monomers.
(b)[1 mark]Explain why water is eliminated when the two monomers react to form the polyester.
(c)[1 mark]State one everyday use of polyesters produced in this way.
(d)[1 mark]Name the type of polymerisation that occurs and give one reason for this classification.
