In chemistry, an enantiomer (/ɪˈnænti.əmər, ɛ-, -oʊ-/ [1] ih-NAN-tee-ə-mər), also known as an optical isomer, [2] antipode, [3] or optical antipode, [4] is one of a pair of molecular entities which are mirror images of each other and non-superposable.

Enantiomers are molecules that have the same molecular formula and connectivity of atoms but differ in their spatial arrangement. More precisely, enantiomers are mirror-image isomers of each other, just like our left and right hands are mirror images of one another. This concept of mirror symmetry is essential for enantiomers.

Enantiomers are a pair of molecules that exist in two forms that are mirror images of one another but cannot be superimposed one upon the other. Enantiomers are in every other respect chemically identical.

2024年1月19日 · Enantiomers are mirror-image stereoisomers with identical molecular structures, distinguished by their non-superimposable nature. They possess a chiral center and exhibit unique optical activities, impacting their interactions with light and biological systems.

2023年1月23日 · Enantiomers are pairs of compounds with exactly the same connectivity but opposite three-dimensional shapes. Enantiomers are not the same as each other; one enantiomer cannot be superimposed on the other. Enantiomers are mirror images of each other.

On the contrary, if the carbon atoms had four different atoms connected it, the mirror image wouldn’t be superimposable to it – they would’ve been enantiomers:. If you feel like this is some kind of trick and the objects are the same, try building the two molecules using a model, and you will see that you won’t be able to repeat identical representations – they are not superimposable.

2024年12月23日 · enantiomer, either of a pair of objects related to each other as the right hand is to the left—that is, as mirror images that cannot be reoriented so as to appear identical. An object that has a plane of symmetry cannot be an enantiomer because the object and its …
