Different types of nylon are identified by the number of carbon atoms in each of its monomers, with the diamine quoted first, followed by the dicarboxylic acid.

a. Draw the skeletal formula of each monomer used to make nylon 6,10.

b. Use the skeletal formulae in part a to draw an equation showing the condensation polymerisation to make nylon 6,10 from a diamine and a dicarboxylic acid.

c. i. Draw the skeletal formula of an alternative monomer to the dicarboxylic acid drawn in part a to make nylon 6,10.

ii. What would be the other product of the polymerisation reaction using the alternative monomer?

d. Explain in terms of structure and intermolecular forces why Kevlar® is such a strong material.
