This module seeks to develop your understanding of the basis of organic chemistry with a focus on small molecules. After an introduction to the key concepts covering understanding of the reactions of organic compounds, including chemical bonds, valence, molecular orbitals and their interactions, you will become familiar with main functional groups (alkanes, alkenes, alkynes, alkyl halides, alcohols, aldehydes, ketones, amines, carboxylic acids, acyl derivatives along with nucleophiles and electrophiles and how to generate them for use in synthesis) in organic chemistry. Additionally, the module provides skills to graphically represent these molecules in three dimensions and illustrate their reactions by using pieces of software routinely employed in pharmaceutical research and development. These are acquired through hands-on experience in computer labs. Building upon these concepts, fundamental properties, preparation, chemical reactivity, commercial significance, reactions, and characterisation of the main classes of molecules will be explored, with an emphasis on stoichiometry. The module looks at the transformations of key functional groups in organic chemistry, followed by an introduction to equilibrium, acids and bases, the 1st, 2nd and 3rd laws of thermodynamics.A part of the module is devoted to tackle reaction mechanisms, introduce aromaticity and the main chemical reactions of benzene and study applications of organic chemistry.Chemical equilibrium will be unravelled, with an emphasis on dynamic equilibrium, the constants Kc and Kp., basic calculations, extent of reaction, solubility equilibria, pH and the main aspects of thermodynamics. Practical hands-on laboratory activities are planned to enhance your understanding and awareness of the main classes of reaction e.g., acid-base and redox titrations, assays for identifications of functional groups and chemical classes etc.
