Web顺反异构 （英語： cis-trans isomerism ），舊称 几何异构 [1] ，是存在于某些 双键 化合物或 环状化合物 中的一种 立体异构 现象。 由于存在双键或环，这些分子的自由旋转受阻，产生两个物理性質或化學性質均不相同的 同分异构体 ，分别称为 顺式 （ cis ）和 反式 （ trans ）异构体。 “顺式加成”指的是从双键或三键的同一侧进行 加成反应 ；“反式加成”指 … WebGenerally the number of isomers increases. You can demonstrate this to yourself by drawing all possible structures for propane (1), butanes (2), pentanes (3), and hexanes (5). One way to think about this is as follows: Each carbon you add can attach to any of the carbons already present in any isomer of the molecule.
