QCE ChemistryPractice Examination 15

This paper covers

• Multi-step organic synthesis pathway design from an alkane to an ester fragrance compound (reaction-type, reagent and condition selection at each step)
• Six core organic reaction types: combustion, free-radical/nucleophilic substitution, elimination, addition (Markovnikov), oxidation, esterification
• Organic structure, IUPAC nomenclature, isomerism and intermolecular-force-based physical property trends across hydrocarbon derivative classes
• Chemical equilibrium: Kc expressions and calculations, reaction quotient Q, and Le Chatelier's Principle (concentration, pressure, temperature)
• Bronsted-Lowry acid-base theory, pH/pOH, strong vs weak acids, Ka/Kb, buffers and volumetric (titration) analysis
• Oxidation-reduction: oxidation states, half-equation balancing, galvanic and electrolytic cells, standard electrode potentials, electroplating and aluminium production (Faraday's laws)
• Industrial synthesis and green chemistry: Haber and contact processes, atom economy, percentage yield, limiting reagent and stoichiometry
• QCAA Assessment Objectives 1-4 (describe/explain, apply, analyse, interpret/evaluate) under the General Senior Syllabus 2025 v1.3
