Modules

CHY3105 : Advanced Organic Chemistry (Distance Learning)

Semesters
Semester 1 Credit Value: 10
Semester 2 Credit Value: 10
ECTS Credits: 10.0

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.

Outline Of Syllabus

Synthesis of Cardonoyls

Teaching Rationale And Relationship

Lectures are delivered electronically and these bring together advanced concepts in organic chemistry, encompassing synthetic and mechanistic principles. Student learning is supported by the provision of worksheets which are returned with formative feedback.

Assessment Methods

The format of resits will be determined by the Board of Examiners
