enantiomers and diastereomers 7.5 STEREOISOMERISM: enantiomers and diastereomers do interchanges in class

STEREOISOMERS Stereoisomers are the same constitutional isomer, but have a difference in the way they are arranged in three-dimensional space at one or more of their atoms. and remember …...

ISOMERS CONSTITUTIONAL ISOMERS STEREOISOMERS ENANTIOMERS DIASTEREOMERS Different compounds with the same molecular formula each isomer could have stereoisomers STEREOISOMERS ENANTIOMERS DIASTEREOMERS double bond or ring with a ring cis/trans ISOMERS both can apply (geometric)

STEREOISOMERS ENANTIOMERS DIASTEREOMERS Stereoisomers whose molecules are non- superimposible mirror images of each other Stereoisomers whose molecules are not mirror images of each other do interchanges in class

7.5 ENANTIOMERS rotate this molecule is chiral non-superimposable mirror images rotate this molecule is chiral note that the fluorine and bromine have been interchanged in the enantiomer do interchanges in class

Stereoisomers whose molecules are not mirror images of each other 7.5 Diastereomers Stereoisomers whose molecules are not mirror images of each other cis/trans isomers do interchanges in class
