【Abstract】 In basic organic chemistry there are rich and varied content and form of quality and quantity, for example, change of bond angles, component of hybridized orbital, reaction temperature, length of carbon chains, number of substituenting group, reagent concentration, pH value and concentration of substance lead respectively to the change of substance chemical property, chemical character, composition of product, nature of substance,property of substance, reaction product, colors of organic indicator and odor; and so on. In practical teaching the students’should be introduced to summing up the law of the change of them, which is of great benefit to enlivening the students’thought, arousing their enthusiasm for study, enriching the interaction in the teaching and improving the teaching quality.更多还原
