5.2 Enantiomers and chiral molecules a Chiral molecule is defined as one that is not superposable on its mirror image The chiral molecule and its mirror image are enantiomers, and the relationship between the chiral molecule and its mirror image is defined as enantiomeric(对映异构) The word chiral comes from the greek word Cheir, meaning hand. That means relationship between left hand and right hand5.2 Enantiomers and chiral molecules • A Chiral molecule is defined as one that is not superposable on its mirror image. • The chiral molecule and its mirror image are enantiomers, and the relationship between the chiral molecule and its mirror image is defined as enantiomeric (对映异构）. • The word chiral comes from the Greek word Cheir, meaning ‘hand’. That means, relationship between left hand and right hand
