Describe the conditions that could be used to hydrolyse $E$ so that a mixture of three amino acids is formed.
Draw the structures of the three amino acids formed in this hydrolysis reaction. The three amino acids should be shown in the correct form for the conditions you selected in a(i).
If a pure sample of $E$ is obtained in aqueous solution, several kinds of intermolecular force may exist between pairs of $E$ molecules. Name three different types of intermolecular force present between pairs of $E$ molecules, stating the groups on the molecules where the forces act.
Polyesters and polyamides are both important kinds of condensation polymer. Draw the structure of a compound that can polymerise to form a polyamide without needing a second monomer.
Draw the structures of two different compounds that can polymerise together to make a polyester with four carbon atoms per repeat unit. Name the two compounds.
