| 摘 要： | 在结构化学教学中,分子所属点群和对称元素的确定是教学的难点和重点.结合具体教学实践,我们对椅式环己烷和S8分子进行了方便确立分子点群和对称元素方面的构型简化.在具体教学过程中,简化后的构型因对称元素的寻找不受图形准确性的影响,所以分子所属点群和对称元素位置容易确定,从而降低了教学难度,病提高了教学质量和效果.

| Abstract: | Determination of the symmetry element and molecular point group is the key and difficult points in the Structural Chemistry Teaching.Based on the teaching practice,the molecular structure of cyclohexane and S8 is simplified for easier determination of the symmetry element and molecular point group.Independent of the accuracy of molecular structure,the symmetry element and molecular point group is relatively easy to determine in teaching process.The application of the simplified molecular structure is of great significance to reducing teaching difficulty and the improvement of teaching. |
