QCE ChemistryPractice Examination 14

This paper covers

• Markovnikov addition and acid-catalysed hydration of unsymmetrical alkenes (regioselectivity via carbocation stability)
• IUPAC nomenclature, isomerism and structure of the 12 hydrocarbon-derivative classes
• Six core organic reactions: combustion, nucleophilic substitution, elimination, addition, oxidation, esterification
• Multi-step organic synthesis pathway design and reagent selection
• Chemical equilibrium: Kc, reaction quotient and Le Chatelier's principle (concentration, pressure, temperature)
• Bronsted-Lowry acid-base theory, pH/pOH, Ka/Kb, weak-acid ionisation and buffer calculations
• Volumetric analysis: acid-base titration stoichiometry and concentration determination
• Redox: oxidation-state assignment, half-equations, galvanic and electrolytic cells, standard electrode potentials, Faraday's laws
• Industrial synthesis (Haber, contact, biodiesel, bioethanol), green-chemistry principles and atom economy
• Stoichiometry: limiting reagent, percentage yield and quantitative problem solving
