对结构化学中价键理论教学的若干思考

通过追踪原始文献,分析结构化学中价键理论部分的教学内容,特别是对氧气分子基态电子结构的处理,发现价键理论不仅能够正确解释或预测分子结构,而且对芳香性、铁磁性等化学键本质的描述表现更优.

Revisit on the Teaching of Valence Bond Theory in the Curriculum of Structural Chemistry

After extensive investigations on the valence bond theory in the curriculum of structural chemistry, it was found that the limitation or even failure of the valence bond theory especially for the double bond electronic structure of oxygen molecule does not exist. Valence theory is capable of not only rationalizing or predicting the molecular structures but also revealing the chemical nature for many properties such as aromaticity and ferromagneticity in comparison with molecular orbital theory.
