Abstract: In the 2017 national college entrance examination, a test question was designed based on the pentazole anion (cyclo-N5-) salt reported by Chinese scholars. Since then, the number of test questions related to polynitrogen compounds has gradually increased. By reviewing the research and development history of polynitrogen compounds and analyzing test questions derived from these materials, scientific inaccuracies were identified in some cases. Therefore, when developing test items in the context of academic exploration, particular attention should be given to ensuring accuracy, relevance, and the backwash effect.

Key words: Test item development, Academic exploration context, Polynitrogen compound, Pentazole anion
