They are either geometrical isomers or compounds containing two or more chiral centres. A Diastereomer is called erythro if its Fischer projection shows similar groups on the same side of the molecule. its mirror image. Answer: c 3. are stereoisomers that are not mirror images. Answer: d 4.

Stereoisomers that are not mirror images

definition of a diastereomers is the stereoisomers that are not enantiomers. Oct 25, 2011 ______ are mirror-image isomers. ______ are stereoisomers that are not mirror images of each other. ______-______ (______) ______ are Stereoisomers are molecules that differ only in the arrangement of bonds in 3D Chiral An object that has a non-superimposable mirror image is said to be One of the most interesting types of isomer is mirror-image stereoisomers, a non- superimposable set of two molecules that are mirror images of one another. Enantiomers: Stereoisomers which are mirror images; Diastereoisomers: Stereoisomers which are not mirror images. The examples of cis- and trans-1 Unlike cis-trans isomerism, this stereoisomerism arises from the ability of molecules to be chiral.

Enantiomers are not superimposable and are the mirror images of each other. Cis and trans or EZ isomers of alkenes are stereoisomers. Since they are not mirror images they are diasterioisomers..
