WebApr 14, 2024 · Chiral molecules are non-superimposable mirror images of each other and exist as enantiomers. The term "chirality" comes from the Greek word "kheir," which means hand, as many chiral objects have handedness, like our hands. Enantiomers: Enantiomers are pairs of stereoisomers that are non-superimposable mirror images of each other. Web1 day ago · Tags; HERO ID. 2854545 Reference Type. Journal Article Title.
