Aims |
|
|
The aim of this module is to introduce students to the basic techniques used in synthetic organic chemistry. |
|
Learning Outcomes |
|
|
Upon successful completion of the module, a student is expected to possess proficiency with basic techniques of synthetic chemistry (setting up reactions, product isolation,purification techniques and analytic characterization). |
|
|
Upon successful completion of the module, a student is expected to have the basic understanding of electronic search methods for chemical information using specialized databases |
|
|
Upon successful completion of the module, a student is expected to have basic ability to interpret 1H NMR, MS and IR spectra of simple organic molecules |
|
|
Upon successful completion of the module, a student is expected to have basic understanding of scientifc writing |

Teaching and Learning Strategies |
|
|
Lecture - lecture |
|
|
Laboratory Work - lab Each lab (six 3-h sessions), the students will perform a new experiment, as described in the content; the students'' performance will be assessed by the demonstrators; demonstrators, instructors and technical staff will be available to provide hands-on advice and guidance to specific technical tasks. |
|
|
Practical - workshops The students are asked to complete a series of assignments (which they can complete before coming to class) and will be assessed on their success by demonstrators. The demonstrators and instructors will be on hand to provide guidance to students as needed. |
|
Syllabus |
|
| 1 |
Lecture 1 (RB): Basic principles of NMR spectroscopy and interpretation of spectra.
Lecture 2 (CC): Good practice and safety in the lab. Introduction to basic separation techniques (filtration, re-crystallisation, thin layer chromatography). Experiment 1: Determination of melting point and analysis of a mixture by thin layer chromatography. Experiment 2: Crystallisation of an unknown compound and identification of an unknown compound using an IR spectrometer. Experiment 3: Separation of benzoic acidand naphthalene by acid-base extraction. Experiment 4: Preparation of3-acetylcoumarin and 3-acetylcoumarin oxime. Experiment 5: Active principles in drug tablets (TLC, MS,NMR and IR interpretation). Experiment 6: Hydrolysis of methyl 2-hydroxybenzoate (methyl salicylate). Workshop 1: Interpretation of MS, IR and 1 H NMR data. Workshop 2: Computer chemical drawing. Structure-based chemical database searching (Beilstein on-line) |

However, if a student misses a workshop for a legitimate reason, he/she will be offered an opportunity to complete all assigned problems independently and his/her solutions will be assessed as if they were performed in class |
