CHY3108 : Advanced Organic Chemistry

Semesters
Semester 1 Credit Value: 20
Semester 2 Credit Value: 10
ECTS Credits: 15.0

Aims

To equip students with the necessary knowledge and understanding for them to study organic chemistry at Stage 4; to further enhance the students’ knowledge of the chemistry of aldehydes, ketones, esters, amides and related species; to allow students to design syntheses of compounds containing carbonyl groups; to illustrate the rich and diverse chemistry of the carbonyl group and to show how this can be logically predicted; to introduce the concept of retrosynthetic analysis; to show how the chemistry of the carbonyl unit can be used in total syntheses. To show the importance of carbonyl reactions in enzyme chemistry. To highlight the use of organo-element compounds in the synthesis and reactions of carbonyl compounds.

Teaching Rationale And Relationship

In lectures students learn advanced concepts in organic chemistry, encompassing synthetic and mechanistic principles. The small group teaching sessions look over these techniques.

In practical classes competencies in practical procedures, observation, record-keeping and report writing, will be taught and learnt.

Assessment Methods

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. Formative assessment in the form of coursework will be set in Semester 1.

The laboratory component practical involves the assessment of a complex selection of skills learnt in about 4 experiments per student, spread over the major areas of inorganic chemistry.
