Enantiomers nonsuperposable mirror images are called enantiomers and are enantiomers with respect to each other
Chlorodifluoromethane is achiral The two structures are mirror images,but are not enantiomers,because they can be superposed on each other
Chirality in Molecules The cis isomer is achiral. The trans isomer is chiral. Enantiomers:nonsuperimposable mirror images,different molecules. same compound different compounds H H CI CI H CI cis-1,2-dichlorocyclopentane trans-1,2-dichlorocyclopentane (achiral) (chiral) Pearson Prentice Hall,In
Stereocenters Any atom at which the exchange of two groups yields a stereoisomer. Examples: >Asymmetric carbons >Double-bonded carbons in cis-trans isomers CH2CH3 CH2CH2CH3 CH2CH3 H:C H3C Br CH(CH3)2 asymmetric carbon chirality centers() eocenters(circled) Copyright0 Pearson Prentice Hall,Inc
