This module explores four important areas in Chemistry:
(i) Thermodynamics and Equilibrium.
The course starts with the concept of internal energy and changes in the internal energy of reactants and products as a reaction proceeds. The enthalpy function, exothermic and endothermic reactions, Hess’ law and bond energies are introduced. The concept of chemical equilibrium and the equilibrium constant is then introduced.
(ii) Chemical Trends in the Periodic Table.
General properties of metals, non-metals and metalloids. Metal and non-metal oxides, and oxide trends across/down the Periodic Table. Chemical Group trends in the s-Block elements. P-Block chemistry: sequential Group discussion (Groups 18-13) to include outer electronic configurations for the Groups and typical chemical reactions of selected main members of the Groups and properties of representative compounds.
(iii) Chemical Kinetics.
This course starts with the introduction of the rate of a reaction and how this can be measured. Then, material on the rate law, reaction order, the Arrhenius equation, the activation energy and the influence of temperature on the rate of a reaction is covered.
(iv) Organic Chemistry.
Material covered includes: Recognising functional groups (alkanes, cycloalkanes, alkenes, alkynes, aromatic hydrocarbons, alkyl halides, alcohols, ethers, amines, carboxylic acids, ketones, aldehydes and amides); The IUPAC system of nomenclature for selected members of these families; Point chirality; R- and S-configurations and the Cahn-Ingold-Prelog rules; Introduction to mechanisms and curly arrows; Nucleophilic substitution reactions, Elimination reactions.
