Chemistry HSC HSC Practice Question 1a – Model and compare the structure

Q1a Chemistry Model and compare the structure Module 7 - Outcome 6

A product designer is choosing a condensation polymer for two different items:

  • Item 1: a reusable hot-food pouch that is repeatedly flexed and washed.
  • Item 2: a lightweight fabric for a sports jersey that must wick sweat and dry quickly.

The designer is considering two polymers:

  • Polymer X is made by condensation polymerisation of hexane-1,6-diamine and hexanedioic acid.
  • Polymer Y is made by condensation polymerisation of ethane-1,2-diol and benzene-1,4-dicarboxylic acid.

Both polymers are produced as long-chain materials and can be spun into fibres. The designer is also considering that both materials may be exposed to warm water and detergents during cleaning.

Question 1a

Model and compare the structure

Module 7 Overview

Students focus on the principles and applications of chemical synthesis in the field of organic chemistry. Current and future applications of chemistry include techniques to synthesise new substances – including pharmaceuticals, fuels and polymers – to meet the needs of society. Each class of organic compounds displays characteristic chemical properties and undergoes specific reactions based on the functional groups present. These reactions, including acid/base and oxidation reactions, are used to identify the class of an organic compound. In this module, students investigate the many classes of organic compounds and their characteristic chemical reactions. By considering the primary, secondary and tertiary structures of organic materials, students are provided with opportunities to gain an understanding of the properties of materials – including strength, density and biodegradability – and relate these to proteins, carbohydrates and synthetic polymers.
