As we move into the second half of year 2, we continue the expansion of core chemistry knowledge in all branches of chemistry. In physical chemistry, students revisit the energy level concept from year 1 and expand it to different types of spectroscopy and more complex molecules and are introduced to the tools of quantum mechanics. In organic chemistry, students are introduced to the idea of retrosynthesis and explore the two-step synthetic design of more complex target molecules. Inorganic chemistry focusses on solid state materials and their analysis by diffraction techniques, while analytical chemistry advances to the science of separation and hyphenated techniques. Sustainable chemistry lectures introduce students to green chemistry in specific industries, renewable carbon resources and life cycle analysis. Support if offered through formative workshops run by academic staff to help practice and apply the core concepts. Assessment is through exam, a group analytical activity and sustainable poster presentation.
