A compulsory 3-lecture course that involves the basics of organic spectroscopy such as nuclear magnetic spectroscopy (NMR), infra-red spectroscopy (IR), ultra-violet spectroscopy (UV) and mass spectroscopy (MS), and the use of these spectroscopic techniques in the identification of organic compounds. This course, also, deals with structures, shapes, preparations and reactions of ethers, phenols and conjugated unsaturated compounds. Structures, properties and reactions of aromatic compounds, including different substitution reactions, are also involved.
