反式异构体通常更为稳定，这并非由于对称性问题，而是因为顺式异构体中的取代基之间存在较高的位阻效应。具体而言，顺式异构体中的两个相同或相似的取代基位于分子链的同一侧，因此彼此之间的距离较近，导致位阻较大。在反式异构体中，取代基位于分子链的相对两侧，它们之间的距离较远，位阻较小。这种...

Cis-Trans Isomers Exhibit a Type of Stereoisomerism Where the Atoms Have Different Spatial Arrangements in 3-D Space. Learn about Cis-Trans Isomers with Examples.
Ring structures or cyclic compounds can also exhibit cis/trans isomerism without the presence of a pi bond. Remember, substituents will be cis and trans if they arelockedin place. Pi bonds are one way to lock them in place. Rings are another matter. ...
