针对中学化学教学中形成原电池可以加快反应速率、溴乙烷的消去反应、酯化反应机理等几个难以理解和容易误判的案例进行探讨,并提出教学建议。 Aiming at the problems of difficult to understand and easy to misjudgment caused by the formation of primary batteries in secondary chemistry teaching, such as accelerating the reaction rate, elimination reaction of bromoethane and esterification reaction mechanism, some teaching suggestions are put forward.
