Module content

Indicative content includes:

• Molecular compounds formed by and / or between p-block elements. Boranes and carboranes – the basis and use of Wades Rules. Closo-, nido-, arachno- cages. Interhalogens and related ions. The inert pair effect. Electron deficient bonding models. Metal-metal bonding in trasnsition metal chemistry.

• Molecular shape. Symmetry in inorganic chemistry. Symmetry operations and elements. Point groups and their assignment. Symmetry labels, as applied to orbitals. Construction of character tables. Tanabe-Sugano and Orgel diagrams.

• Molecular orbital diagrams of heterodiatomics and small molecules e.g. H2O.

• Further transition metal chemistry. Crystal-field theory vs molecular orbital appoach. The Spectrochemical series linked to molecular orbital and pi-donor or acceptor ligands. Reaction mechanisms for ligand substitution (associative, dissociative, A/D) and electron transfer (outer sphere, inner sphere) in transition metal chemistry. Simple magnetochemistry.

• Introduction to f-block chemistry. Lanthanide contraction. Prevalence of the +3 oxidation state, and exceptions. Comparisons to d-block. Simple magnetochemistry. Oxidation states in oxides and aqueous chemistry.

• Laboratory experiments on the synthesis, quantitative and qualitative analyses on topics in main group, d-block and solid state chemistry.

Assessment pattern

Alternative Assessment

Failure in the laboratory may require re-assessment through a defined practical examination

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate successful achievement of the learning outcomes.

Thus, the summative assessment for this module consists of:

• 1.5 hour examination (80%) addressing LO1-LO4


• Laboratory portfolio (20%) addressing LO1-LO4

Formative assessment

2 hours of tutorial sessions addressing LO1-LO4 through set problems Laboratory portfolio consists of both formative and summative experiments addressing LO4

Feedback

Feedback on problem sets is provided in each tutorial 2 revision classes provide feedback on student’s approach to past examination problems

Feedback on laboratory performance is provided in each pre-lab session – 1 per week before each laboratory session

Module aims

• To show how the fundamentals of structure, bonding, substitution and redox reactions and spectroscopy are linked. How these may be applied to explain the chemistry and properties of selected p-. d- and f-block elements.
• To introduce concepts in molecular symmetry – from the definition of symmetry operations to the anatomy of character tables.
• To introduce electron counting theories through the introduction to Borane chemistry and Wades rules, as expained through a molecular orbital approach.
• To expand on d-block transition metal chemistry to include a review of crystal field theory and its link to molecular orbital theory. Thus, explain the Spectrochemical series.
• To review the reaction mechanisms of transition metal complexes for ligand exchange and redox.
• To introduce the chemistry of the f-block with an emphasis on the differences between d- and f-block chemistry, trends and reactivity.

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

Transfer and embed knowledge, and encourage students to understand and further investigate key aspects of inorganic chemistry in terms of the nature, structure, bonding, reactivity of selected p-, d- and f-block elements and compounds.

The learning and teaching methods include:

• 2 or 3 hours of lectures per week – total 25 hours


• Two 1 hour revison classes


• 6 laboratory classes, each with a 1 hour pre-lab session


• 2 hours of tutorials

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
