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.
Structural isomers have the same molecular formula but a different bonding arrangement among the atoms. ... The simplest forms of stereoisomers are cis and trans isomers, both of which are created by the restricted rotation about a double bond or ring system.What...

反式更稳定,不是因为对称因素,很简单的理由:是因为顺式结构取代基的位阻(离得比较近)比反式的位阻高。
cis&trans •在一些学科当中,我们常将这两个词翻译为“顺式”与“反式”或者“顺”与“反”。在生物学当中 •1、在分子生物学当中,cis(顺式)一般指位于同一个染色体/核苷酸片段上,而trans(反式)一般指位于不同染色体/核苷酸片段上。比如 ·顺式作用元件与反式作用因子(cis-actingelement&trans-...
