Prerequisite Modules:

Rationale and Purpose of the Module:

To introduce the student to fundamental aspects of organic chemistry eg the different families of compounds- their nomenclature, structure (2D and 3D) and isomerisation (if any). To highlight the functional group of each family and relate structure to reactivity; to examine associated reactions/reaction mechanisms of the different functional groups; to introduce aromatic chemistry and study the chemical behaviour of aromatic compounds; to highlight current trends and applications in the areas of organic chemistry. To carry out practical work to support and reinforce some of the theoretical aspects encountered; to encourage self-directed learning through the use of software and web sources.

Syllabus:

Aliphatic Hydrocarbons: Alkanes/Cycloalkanes/Alkyl Groups/Alkenes/Cycloalkenes/Alkynes: Nomenclature; Structural formulae (2D&3D); Isomerisation; Reactions: Combustion and Free Radical Rxns (Alkane/Cycloalkanes); Electrophilic Addition Rxns., Carbocations; Polymerisation;(Alkenes/Cycloalkenes/Alkynes). Occurrence/Uses. Environmental factors/current trends. Haloalkanes: Structural formulae; Nomenclature; Substitution/Elimination Reaction Mechanisms- SN1, SN2; E1, E2. Alcohols/Ethers: Structural formulae; Nomenclature; Classification; Physical properties; Occurrence and Uses. Alcohols only:- Acidity; Preparation; Reactions: Oxidation, Esterification. Aldehydes/ Ketones: Structure & Basicity of the Carbonyl Group; Nomenclature; Properties; Preparation; Typical Carbonyl Group Reactions (Nucleophilic Addition Reactions); Imine formation; Reaction with Grignard Reagents; Synthesis; Occurrence/Applications. Carboxylic Acids and Carboxylic Acid Derivatives: - Esters, Acyl Halides, Acid Anhydrides and Amides. Functional Group; Nomenclature; Physical Properties; Acidity of the Carboxyl group; Preparation; Nucleophilic Acyl Substitution Reactions (Simple Carboxylic Acids and Esters only). Amines: Classification; Aliphatic and Aromatic Amines; Reactions; Occurrence. Aromatic Hydrocarbons: Benzene and Benzenoid Compounds. Aromaticity- Huckel Rule; Structural Formulae; Nomenclature, Electrophilic Aromatic Substitution Rxns Mechanism; Few examples. Occurrence/Uses.

Learning Outcomes:

Cognitive (Knowledge, Understanding, Application, Analysis, Evaluation, Synthesis)

1. State the systematic name for simple organic compounds belonging to all families of compounds. 2. Draw the chemical formulae and structural formulae (condensed, expanded, skeletal) for simple organic compounds. 3. Define and apply the various types of isomerisation-structural, conformational, geometric and optical to compounds, where applicable. 4. Draw the 3D structure of various compounds belonging to the different families of compounds; demonstrate that the 3D structure of the compound is dictated by the type of hybridisation pertaining to the key atoms of the functional group present in the molecule. 5. Recognise functional group(s) present in a compound and consequently predict the chemical behaviour of the compound; draw mechanisms for some of the main reactions encountered. 6. Identify aromatic compounds on the basis of Huckel¿s Rule and illustrate the mode of behaviour of benzene-type compounds with reaction example and mechanism. 7. Recognise the chemistry at play in a given set of synthetic sequences and identify key reagents required for the transformations to occur.

Affective (Attitudes and Values)

1. Relate organic chemistry to the world around us eg natural occurrence, associated environmental and societal issues, current trends. 2. Grasp the importance of comprehending organic chemistry rather than reliance on memory work. 3. Demonstrate a keenness for self-directed learning. 4. Appreciate the historical context of organic chemistry/key organic reactions from a pedagogical point of view.

Psychomotor (Physical Skills)

On successful completion of this Module the student should have acquired skills in the 1. Assembly of Quickfit glassware for operations such as reflux and distillation. 2. Performance of recrystallization/extraction techniques; identification of known/unknown organic compounds 3. Safe practice in the use and disposal of a variety of hazardous type chemicals and the know-how in obtaining data on the safety of the various chemical encountered. 4. Presentation of a record of one¿s own results in the form of a brief, organized report.
