Full description at: http://www.chem.utas.edu.au/staff/blackman/shareware/torganal.htm This site contains a lot of great educational material for organic chemistry. Torganal simulates the laboratory process of identifying unknown organic compounds (at early university level). By using this program before starting laboratory work, students can rehearse the strategy of identifying an unknown in a situation free from the additional uncertainties of performing unfamiliar laboratory tasks and then having to rely on the results. Interpretation of spectra may also be practised. Torganal has been reviewed very favourably in England and Australia and is now being used by hundreds of students each year in universities in countries throughout the world (mainly Australia, England, and USA). Version 4 of the program was released in early 1996. AJ Blackman, 'A Pedagogical Approach to Qualitative Organic Analysis-Simulating the Integration of Wet Tests, Spectroscopy and Common Sense', J.
