化学软件辅助下的高中化学可视化教学——芳香烃的取代反应

Visual Teaching of Senior High School Chemistry with the Aid of Chemistry Software:Substitution of Aromatic Hydrocarbons

利用Gaussian系列软件与ChemDraw软件设计并呈现“芳香烃取代反应”的静电势图、多信息势能剖面图、原子电荷分布图,使取代基对苯环活性的影响等抽象概念可视化。通过直观的图形,培养学生从化学键、基团间的相互影响等认识角度学习有机化学,激发学生的化学学习热情。

With the combination of Gaussian series software and ChemDraw software,the visualization of electrostatic potential diagrams,multi-information potential energy profiles,and atomic charge distribution diagrams of"aromatic hydrocarbon substitution reactions"is provided to visualize abstract concepts such as the effect of substituents on benzene activity.Through visual graphics,students are trained to learn organic chemistry from the perspective of understanding chemical bonds,interactions between groups,and are motivated to learn chemistry.
