CHEM1036 Fundamentals of Inorganic Chemistry II

Module Overview

Aims and Objectives

Module Aims

The aim of this course is to provide a core for future studies in chemistry and allied subjects, in aspects of inorganic chemistry as specified below and an introduction to basic practical skills including safe working practices (risk, hazard and control measures), laboratory report writing (written and verbal communication of results), error and accuracy Teaching in this course recognises the diversity of our intake in terms of A level syllabus followed and choice of non-Chemistry A level subjects (maths, physics, etc.). Theory component: The aim of the NMR section of the unit is to provide an introduction to modern NMR spectroscopy, and structure prediction and solution using the technique. The aim of the Transition Metal Elements section of the unit is to provide an introduction to coordination chemistry and the chemistry of compounds of the transition metal elements. The primary objective of the Main Group Elements section of the unit is to provide an introduction to the ‘descriptive chemistry’ of the elements and to demonstrate how electronic properties can influence reactivity, atomic size and other physical and chemical properties of the elements. Practical component: The aim of the practical component of the module is to provide students with the skills that will be needed in their future practical work. Instruction is provided regarding the in the presentation of practical reports, awareness of health and safety procedures, practical skills in the laboratory (and the theory on which they are based) and problem solving in the practical situation. Students will undertake a series of experiments based on the following topics: • Transition metal complexes • Copper glycinate • Iodine clock • pKa of an indicator • Siloxanes • Demonstration chemistry Each experiment is also preceded by a prelaboratory exercise that involves a combination of audio visual resources, accessible via Blackboard, that will help prepare you for the experimental work. A short quiz based on this content is to be completed before starting practical work. There are separate learning outcomes for each experiment and these are further specified in the practical scripts.

Learning Outcomes

Learning Outcomes

Having successfully completed this module you will be able to:

  • Describe the physical basis, the limitations and the information available from NMR spectroscopy as a structural method.
  • Present the results of a practical investigation in a concise manner.
  • Qualitatively predict and/or interpret the NMR spectra of simple molecular species.
  • Qualitatively discuss simple trends in the physical properties of transition metals and their formation of coordination complexes with ligands.
  • Describe bonding models that can be applied to a consideration of the properties of transition metal compounds.
  • Recognise fundamental variables and general trends across the periodic table and predict molecular geometries and structures, recognising the importance of inert-pair effect, coordination geometries, oxidation state, electronegativity, ionisation energy, VSEPR, etc..
  • Identify the structures and properties of some important Groups 13-18 elements and their compounds with a view to gaining a better understanding of broad diversity in their chemical properties, their importance in the natural environment and their role in the development of bonding theories.
  • Evaluate the risks associated with an experiment and understand how to mitigate against those risks.
  • Set up glassware and apparatus to conduct experiments in Inorganic Chemistry.
  • Interpret data from a range of physical techniques to characterise inorganic componds.

Assessment

Assessment Strategy

The practical and theory (examination plus tutorial) components must be passed separately at the module pass mark for the student’s programme, i.e. 40% if core, 25% if compulsory or optional (if compensation is allowed). All absences from practical sessions must be validated. Unexcused absences will result in failure of the module.

Linked modules

Repeat year externally: allowed if practical component passed. The practical marks are retained, the theory assessment is exam only. Repeat year internally: note that practical may be reassessed by resubmission of reports or repeated.
