Consider stereoisomers of 1,2-dichlorocyclopentane: same compound different compounds H H cis-1,2-dichlorocyclopentane trans-1,2-dichlorocyclopentane (achiral) (chiral) ●201白onEonir The cis isomer has a superimposable mirror image-achiral. The trans isomer is non-superimposable on its mirror image-chiral. Such pairs of non superimposable mirror images are called enantiomers. Every chiral compound has enantiomers. Achiral compounds do not have enantiomers.
