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. WebTraditionally, double bond stereochemistry was described as either cis (Latin, on this side) or trans (Latin, across), in reference to the relative position of substituents on either side of a double bond.

Cis-trans isomeria

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 … WebThere are no cis or trans isomers in benzene ring because there is only one additional bond to C outside the benzene ring. Because the benzene C has a (delocalized) double bond it has trigonal planar geometry and the bond is in the plane of the benzene ring. As a result there are no cis/trans possibilities on the flat planar benzene ring.
