Brief Review of Isomerism
D1 Stereoisomers Compounds which have the same number and types of atoms,but are nonetheless different chemical compounds are called isomers. Isomers which differ only in the way in which they are arranged in space are called stereoisomers. •由于单键旋转而使分子中原子或基团在空间不同的排 列，这种不同的排列形式称为构象异构 (conformation)。由此产生的一系列分子形象互称为 构象异构体
