Introduction to Chemical Concepts (CHE145)

Organisational Unit Chemistry and Physics
Credit Points 3
Availability MURDOCH: S2-internal, S2-external
Teaching Timetables Murdoch S2
Description This unit provides principles of physical, inorganic and organic chemistry that are required for further studies in the chemical and related sciences. Topics covered include electronic structure, molecular orbitals and reactivity, principles of spectroscopy, physicochemical properties of solids, liquids and gases, trends in properties of inorganic compounds, Lewis acids and bases, nomenclature, isomerism and basic reactions of coordination compounds, redox reactions and electrochemistry, and fundamentals of organic reaction mechanisms. These concepts are supported by practical exercises in the laboratory.
Unit Learning Outcomes On completion of this unit students should be able to:
ULO1 Understand the relationship between electronic structure (quantum numbers), molecular orbitals and reactivity.
ULO2 Recognise the basic principles of spectroscopy and applications for characterisation of compounds.
ULO3 Apply the nomenclature of coordination compounds, describe different forms of isomerism and identify basic reactions of coordination compounds.
ULO4 Develop an understanding of the stability, structure and properties of pure substances in different states of aggregation; explain phase transitions; describe the properties of real gases, liquids and solids, including crystal structures and their determination.
ULO5 Understand redox reactions and basic electrochemistry.
ULO6 Recognise trends in properties of elements and apply the concept of hard and soft Lewis acids and bases to reactions and equilibria.
ULO7 Use curved arrow notation to represent the mechanisms of reactions studied and recognise factors that contribute to the stability of chemical species.
ULO8 Recognise that many reactions of organic compounds are interactions between nucleophiles and electrophiles and identify and write equations for substitution and elimination reactions of aliphatic compounds, and addition reactions of alkenes.
Timetabled Learning Activities Lectures: 3 x 1 hour per week; laboratories: 1 x 3 hours per week; tutorials: 1 hour per week.
External students: Compulsory attendance at a 5 day on-campus laboratory session.
Unit Learning Experiences The approach to learning in this unit is via:
(1) Lecture presentations of fundamental chemical concepts, which will be required for further studies in Chemistry and related sciences such as Extractive Metallurgy and Chemical Engineering.
(2) Practising various applications of these concepts through group learning tasks in workshops and especially in the chemical laboratory. Immediate feedback will be provided by experienced tutors and lecturers.
(3) Using online components comprising materials, discussions, quizzes, lecture recordings and assessment activities to encourage a 'deep approach' to learning.
Other Learning Experiences For external students there is compulsory attendance at a 5 day on-campus laboratory session.
Assessment Assessment for both internal and external students will be based on:
(i) online tests 20 %
(ii) laboratory work 30 %
(iii) final examination 50 %.
To achieve a pass in the unit students must: satisfactorily complete the laboratory section and achieve a total of equal to or greater than 50% as a combined mark. Assessment of laboratory classes is based on completion of prelab quizzes, participation in the experimental learning activities and written reports. The two online tests (quizzes) provide ongoing assessment at intervals throughout the teaching period. The final exam assesses understanding of concepts as well as problem solving skills. All unit learning outcomes are assessed in the online quizzes, labs and final exam.

Internet Access RequirementsMurdoch units normally include an online component comprising materials, discussions, lecture recordings and assessment activities. All students, regardless of their location or mode of study, need to have access to and be able to use computing devices with browsing capability and a connection to the Internet via Broadband (Cable, ADSL or Mobile) or Wireless. The Internet connection should be readily available and allow large amounts of data to be streamed or downloaded (approximately 100MB per lecture recording). Students also need to be able to enter into online discussions and submit assignments online.
