To introduce the basic concepts upon which the understanding of organic chemistry depends, including structure, bonding and mechanism (arrow pushing) in the context of key reactions of organic chemistry. To build upon these basics to develop the concepts and knowledge essential to a sound understanding of modern organic chemistry, including the characteristic properties of organic functional groups (FGs), their interconversions, and their spectroscopic identification.
After studying this unit, students should be able to:
* Describe the structure and bonding of simple organic molecules in order to explain their chemical behaviour.
* Apply nomenclature, notation and diagrams to describe structures and reactions.
* Describe and explain the general properties, reactions, mechanisms and methods of synthesis for monofunctionalized aliphatic and aromatic compounds including a range of transformations that can be used to functionalise an aromatic ring.
* Describe and explain the mechanisms of nucleophilic aliphatic substitution and elimination reactions and of electrophilic addition to alkenes.
* Describe and explain the mechanisms of nucleophilic addition and substitution reactions of the carbonyl group and condensation reactions.
* Explain the stability of aromatic compounds and compare their reactivity with that of alkenes and carbonyls and how this affects their reactivity.
* Apply the methodology of FG interconversions in the synthesis of academically and commercially important target molecules.
* Select appropriate techniques (IR, NMR and UV and mass spectroscopy) to identify organic compounds in a range of situations.
* Solve characterisation problems in organic spectroscopy.
