卤代烃化学性质的教学是该章节的重点和难点。从基本概念入手，通过对两类反应机理和影响因素的讲解，可以让学生较为轻松地突破难点，将α-C设计在一个假想平面上讲解亲核取代和消去反应机理，方便学生对亲核取代和消去反应机理和有关立体化学的理解和掌握。

The teaching of the chemical properties of halohydrocarbon is both the focus and the difficulty in the chapters concerned. With the basic concepts clarified, the elaboration of the two reactions and influential elements can make students easily accessible to the teaching difficulties. With the design of α-C on an imagined plane, the elaboration of the mechanism of the two reactions can promote students’ understanding and mastery of the mechanism of nucleophilic substitution and elimination reaction.
