1.1 Introduction Organic chemistry is the study of the compounds of carbon 1.3 The structural theory of organic chemistry

18.1 Introduction The carboxyl group, -COOH, -CO2H, is one of the most widely occurring functional groups in chemistry and biochemistry. Not only are carboxylic acids themselves important, but the carboxyl group is the parent group of a large family of related compounds

15.1 Electrophilic aromatic substitution reactions These reactions are of the general type shown below;

12.1 Introduction Systems that have a p orbital on an atom adjacent to a double bond---molecules with delocalized pi￾bonds– are called conjugated unsaturated systems

1. 运用逆合成法对目标分子进行剖析，最终确定合成所需的起始原料。这就要求掌握各类化合物的拆分方法。 2. 以剖析为依据，写出合成方案

一. 电环化反应(Electrocyclic Reactions) 在光或电的作用下，共轭烯烃转变为环烯烃或它的逆反应——环烯烃开环变为共轭烯烃的反应都称为电环化反应
