External repeat only possible if lab module is already passed.
Aims and Objectives
Knowledge and Understanding
Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:
- Recognise the properties of reagents and solvents and how these relate to their use in organic reactions
- Predict the outcomes of reactions based on the properties of the functional groups that are present.
- Recognise reactive centres in organic molecules and the types of reactions that they can undergo.
- Draw simple mechanisms to explain the outcomes of reactions.
Subject Specific Practical Skills
Having successfully completed this module you will be able to:
- Meet the learning outcomes of a co-requisite practical module.
