2016-01-20 Enantiomers are chemical isomers that are non-superimposable mirror images of each other. Examples of enantiomers are provided here with a detailed explanation and FAQs Note that the isomers fall into pairs of enantiomers, 2R,3R being the mirror image of 2S,3S and 2R,3S the mirror image of 2S,3R. Because they are now mirror images, these pairs obviously have identical physical properties and rotate the plane of polarized light by equal amounts in opposite directions. I and II i.e.

Enantiomers differ in their configuration (R or S) at the stereogenic center.

E) not isomeric. Chapter 5 2 5. Pairs of enantiomers are: CH2CH2CH3 H3C Cl CH3 CH2CH2CH3 Cl CH3 Enantiomers are isomers that are mirror images of each other and that differ in shape due to the presence of an asymmetric carbon, one that is attached to four different atoms or groups of atoms.

Learn vocabulary, terms, and more with flashcards, games, and other study  What's a racemic mixture or racemate? an equimolar mixture of two enantiomers that shows no rotation of plane-polarized light (zero optical rotation). Enantiomers are stereoisomers whose molecules are non-superimposable mirror images of one another. Isomers that are mirror images of each other. Enantiomers.
