Aims
To provide a thorough understanding of the influence of conformational and stereoelectronic effects on the reactivity of organic compounds; to show how mechanisms of some organic reactions have been investigated and to present the currently accepted mechanisms of these reactions; to provide an understanding of mechanistic and synthetic chemistry; to consider the chemistry of aromatic systems; to provide an understanding of polymer characterization and methods of characterization; to understand fundamental mechanistic differences between step-growth and chain growth polymerizations; to show how the most commonly utilised classes of polymers are synthesized and to outline their properties.

Teaching Rationale And Relationship
The important basic principles of organic chemistry introduced in Stage 1 will be reinforced and built on by material covered in the lectures. This will be supported by tutorials that will allow small groups of students to tackle an array of different problems associated with the lecture material and help prepare for the assessment.
Assessment Methods
The format of resits will be determined by the Board of Examiners
Exams
| Description | Length | Semester | When Set | Percentage | Comment |
|---|---|---|---|---|---|
| Digital Examination | 150 | 2 | A | 100 | Invigilated mix of online MCQs and written questions. Online assessment as alternative in the case of no PiP examinations |
Formative Assessments
Formative Assessment is an assessment which develops your skills in being assessed, allows for you to receive feedback, and prepares you for being assessed. However, it does not count to your final mark.
| Description | Semester | When Set | Comment |
|---|---|---|---|
| Prob solv exercises | 2 | M | N/A |
Assessment Rationale And Relationship
The summative written examination will assess the level of knowledge and understanding of all aspects of the module. The examination will present students with questions from a selection of topics learnt throughout semester 1 and 2 module content.
Formative assessment will allow students to gain feedback during the module.
