AQA A2 Level Chemistry (2421)

A2 Unit 4 - CHEM4 : Kinetics, Equilibria & Organic Chemistry This unit develops the concepts of Physical Chemistry introduced at AS. Kinetics and Equilibria are both treated quantitatively. Acids, bases and buffer solutions and the changes in pH during titrations are considered.  The study of Organic Chemistry is extended to include compounds containing the carbonyl group, aromatic compounds, amines, amino acids and polymers. The final section examines the way in which spectroscopic techniques are used to determine the molecular formulae and structures of organic compounds. The emphasis is on problem solving rather than on spectroscopic theory. 4.1 Kinetics 4.2 Equilibria 4.3 Acids and Bases 4.4 Nomenclature & Isomerism 4.5 Compounds containing the Carbonyl group 4.6 Aromatic Chemistry 4.7 Amines 4.8 Amino Acids 4.9 Polymers 4.10 Organic Synthesis and Analysis 4.11 Structure Determination

A2 Unit 5 - CHEM5 : Energetics, Redox & Inorganic Chemistry This unit extends the concepts of Energetics introduced at AS to Born Haber cycles for ionic compounds.  The Second Law of Thermodynamics, involving Entropy and Gibbs Free Energy is used to consider the idea of spontaneous change.  Redox, introduced at AS, is made quantitative by the introduction of Electrode and Cell Potentials and the application to fuel cells.  The Inorganic Chemistry component looks at periodicity in chemical properties of the elements and their oxides in Period 3.  Transition Metals are introduced, considering especially the formation of coloured complex ions and redox behaviour.  The final topic brings together many aspects of the AS and A2 level Units. 5.1 Thermodynamics 5.2 Periodicity 5.3 Redox Equilibria 5.4 Transition Metals 5.5 Reactions of Inorganic Compounds in Aqueous Solution
