Abstract:

The tasks from the 33th Chinese Chemistry Olympiad (Preliminary Test) were analyzed and solved in detailed step-wise fashion. The requirement for an advanced chemistry knowledge background was loosened in the current tasks; more emphases were placed on the ability of deductive reasoning and comprehensive thinking. In this manuscript not only the systematic analyses for all tasks were provided, but also the readers would be guided to solve the problems by themselves in an intuitive manner. For selected tasks the scientific background and challenging bonus tasks were also introduced.

Key words: Chinese Chemistry Olympiad, Guided solutions
