Part II 1. Course Aims: This course aims to provide students with knowledge of the various principles of inorganic chemistry as well as practical experience in the synthesis, analysis and characterization of inorganic compounds 1
2. Course Intended Learning Outcomes (CILOs) Upon successful completion of this course, students should be able to: No. CILOs Weighting 1. Determine the symmetry elements, the symmetry operations and the point group of a molecule; and predict the infrared and Raman active vibrational modes of that molecule. 2. Explain the bonding and properties of a molecule using molecular orbital theory. 3. Explain the spectroscopic and magnetic properties of transition metal complexes using ligand field theory. 4. Describe the bonding, structures, properties and reactivity of organometallic compounds containing carbon monoxide, alkene, alkyne arene and cyclopentdienyl ligands 5. Design and implement the synthesis, purification and characterization of inorganic compounds in the laboratory. 3. Teaching and learning Activities (TLAs) (designed to facilitate students achievement of the CILOs) ILO No TLAs Hours/week CILO 1 Teaching and learning will be based of large and small group activities in which the principles and applications of group theory will be examined and discussed. Small group activities would involve building up of various molecules using models to examine their symmetry. CILO 2 In large and small group activities the basic concepts of molecular orbital theory will be examined and discussed. CILO 3 In large and small group critical evaluation tasks students will discuss and rationalise the various properties of transitional metal complexes using ligand field theory. CILO 4 Teaching and learning will be conducted in large and small groups in which the properties of various organometallic compounds will be examined and discussed. CILO 5 Students (in groups of two to three) will design and take part in laboratory work in which they will acquire skills in the synthesis, purification and characterization of inorganic compounds. Students will analyse their data and present their results in the form of written reports and oral discussions. The TLAs provided above are indicative of the likely activities that students will undertake in this course. Final details of the individual course components, including large and small group teaching sessions, case studies, discussions and oral presentations, will be provided in the student course documents distributed at the commencement of the course. 2
4. Assessment Tasks/Activities (designed to assess how well the students achieve the CILOs) ILO No Type of assessment tasks/activities Weighting CILO 1 Short quizzes and an examination, which will test the students concept of group theory and symmetry will be given. Practical test during tutorial class will be conducted in which students will be required to deduce the point group of a molecule by examining a molecular model. CILO 2 CILO 3 CILO 4 CILO 5 examination to test the students ability to apply molecular orbital theory to explain the bonding and properties of molecules will be conducted. examination to test the students ability to predict and explain the properties of transitional metal complexes using Ligand Field Theory will be conducted. examination will be conducted to test the students understanding of the basic principles of organometallic chemistry Students performance during laboratory sessions will be evaluated. Laboratory reports of students will be examined. Remarks The Assessment Tasks and Activities provided above are indicative of those that students will undertake in this course. Final details of the individual assessment, including short quizzes, tutorial assignments, discussions, case/visit reports, oral presentations and end-of-course examination will be provided in the student course documents distributed at the commencement of the course. Starting from Semester A, 2015-16, students must satisfy the following minimum passing requirement for BCH courses: A minimum of 40% in both coursework and examination components. 5. Grading of Student Achievement: Refer to Grading of Courses in the Academic Regulations (Attachment) and to the Explanatory Notes. Grading will be based on students performance in assessment tasks/activities. Allocation of marks will be as follows: Coursework (including visit reports, tutorial assignments/quizzes and group presentations), 30%; Examination (3 hrs), 70% (see above table under Assessment Tasks/Activities). 3
