有机合成与推断题是高考中的重头戏,主要考查各种有机物、官能团的性质,以及各种转化关系的综合应用,并结合计算在新情境下加以迁移。试题常以新药、新材料的合成为背景,同时引入新信息,要求学生具备一定的自学能力,能迅速捕捉有效信息,并使新旧信息产生联系,将新信息分解、转换、重组,从而解决问题。一、有机合成有机合成主要是利用一些基本原料(如甲烷、乙烯、乙炔、丙烯、丁二烯、苯、甲苯、苯酚、卤 Organic synthesis and inference questions is the highlight of the college entrance examination, the main test of the various organic compounds, the nature of the functional groups, as well as a comprehensive application of a variety of conversion relations, combined with the calculation in the new situation to be migrated. The test questions are often based on the synthesis of new drugs and new materials. At the same time, new information is introduced to require students to possess certain self-learning abilities, to quickly capture valid information, to make contact with new and old information, to resolve, transform and reorganize new information so as to solve the problem . First, organic synthesis Organic synthesis is the use of some basic raw materials (such as methane, ethylene, acetylene, propylene, butadiene, benzene, toluene, phenol, halogen
