Teaching Rationale And Relationship
In lectures students learn advanced concepts in the organic chemistry of reactions involving cyclic transition states which, encompasses synthetic, theoretical and mechanistic principles. In workshops they apply learnt material to solve problems.
The format of resits will be determined by the Board of Examiners
Assessment Rationale And Relationship
The examination will test the students’ knowledge and understanding of the content of this module in the context of both synthetic and mechanistic chemistry.
Study Abroad students may request to take their exam before the semester 1 exam period, in which case the format of the paper may differ from that shown in the MOF. Study Abroad students should contact the school to discuss this.
