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. ...
