QCE Chemistry study guide
QCE Chemistry · Work through your exam, one topic at a time.
QCE Chemistry is a senior secondary subject in the Queensland Certificate of Education, the school qualification awarded to students who complete Year 11 and 12 study in Queensland, Australia. It suits students who want a science-based pathway into university courses such as chemistry, pharmacy, medicine, engineering, environmental science or education, and who are willing to build fluency in both quantitative problem solving and extended written explanation. Study is organised around four areas: chemical fundamentals covering structure, bonding, properties and reaction types; molecular interactions and reactions, including organic chemistry and reaction pathways; equilibrium, acids and redox; and structure, synthesis and design, which draws the earlier ideas together in applied and investigative contexts. Assessment combines school-based tasks with external assessment set by the Queensland Curriculum and Assessment Authority, and the external exam emphasises short-response questions, calculations, data interpretation and extended responses rather than simple recall. The QCE Chemistry study guide has 4 sections and about 1,462 words.
01Chemical Fundamentals: Structure, Properties and Reactions
Start with the periodic table as a predictive tool: effective nuclear charge, atomic radius, ionisation energy and electronegativity trends explain bonding type. Distinguish ionic (lattice of ions, electrostatic attraction), covalent molecular (discrete molecules, weak forces between them), covalent network (continuous lattice, e.g.

This domain links intermolecular forces to physical behaviour and to reaction pathways. Know the hierarchy: dispersion forces (present in all molecules, stronger with more electrons and greater surface area), dipole–dipole interactions, and hydrogen bonding (N–H, O–H, F–H donors).

Equilibrium is dynamic: forward and reverse rates are equal and concentrations remain constant, not equal. Write and use Kc and Kp expressions, apply Le Chatelier's principle qualitatively, and use reaction quotient Q to predict direction.
364 words, about 2 min04Structure, Synthesis and Design
This domain integrates structure determination with purposeful synthesis. Know functional groups and IUPAC naming, isomerism (chain, position, functional group, and stereoisomerism including cis–trans and optical isomers with chirality), and how shape affects biological and material function.
