The following concepts are being covered: Review of the qualitative tests for the following functional groups: alkene, phenol, alcohol, aldehyde, ketone, carboxylic acid, ester. Review of IR spectroscopy- how does it work; use of infrared spectrum to identify the presence of functional groups in an organic compound. Review of Mass spectroscopy – how does it work; use of molecular ion peak and fragmentation peaks in a mass spectrum to find the molecular mass and to identify parts of an organic structures. Combine evidence from IR and mass spectra to deduce isomers of organic structures- various questions to complete. Elemental analysis - to deduce the empirical formula of a compound from its mass composition. Combine evidence from elemental analysis, IR spectra, mass spectra and NMR spectra, to deduce structures of organic structures- many exam questions to select from. The workbook is for the students to complete. It contains varies activities to achieve the learning outcomes for Combined Techniques.
