Theoretische Aufgaben und Laborarbeiten aus dem breiten Spektrum der Chemie standen auf der Agenda des viertägigen Landesseminars zur Vorbereitung auf die 44. "Internationale Chemie-Olympiade" (IChO). Die 20 besten Wettbewerbs-Teilnehmer aus NRW nutzten das intensive Trainingsseminar vom 4. bis 7. Februar 2012 bei Bayer in Leverkusen, um der im Sommer dieses Jahres in Washington D.C. (USA) stattfindenden Internationalen Chemie-Olympiade einen großen Schritt näher zu kommen. Von den Nachwuchs-Chemikern waren präzise Analysen und ein fundiertes Fachwissen gefordert: Neben anspruchsvollen Klausur-Aufgaben und Übungen beschäftigten sich die jungen Forscher mit der Reaktionskinetik und führten im Labor eine Estersynthese durch.
