Enantiomers are stereoisomers that are non-superimposable mirror images. A molecule with 1 chiral carbon atom exists as 2 stereoisomers termed enantiomers (see the example below). Enantiomers differ in their configuration (R or S) at the stereogenic center. Configuration
If yes and they are non-superimposable mirror images, then these are enantiomers If no, then these are diastereomers Note that the term diasteromers is therefore quite general and other types of stereoisomers are subsets of the diastereomer group e.g. cis-trans isomers or conformational isomers
6 E.M. Ulrich et al. chiral (Nasipuri 1991 ; IUPAC 2006 ) . These conditions result in stereoisomers that are also nonsuperimposable mirror images, and, thus constitute a pair of enantiom- Chapter 5 4 Stereoisomers Enantiomers: Nonsuperimposable mirror images, different molecules with different properties. 5. Chapter 5 5 Chiral Carbons • Carbons with four different groups attached are chiral. • It’s mirror image will be a different compound (enantiomer).

Molecules that are nonsuperimposable (nonidentical) mirror images of each other are a type of stereoisomer called enantiomers Stereoisomers that are nonsuperimposable mirror images of each other. 2011-10-25 How to solve: Molecules that are non-superimposable (non-identical) mirror images of each other are stereoisomers of a specific type called: a. Enantiomers are stereoisomers that are non-superimposable mirror images. Enantiomers have identical chemical and physical properties in an achiral environment The challenge of many chemistry students studying stereochemistry emerges in the distinction between enantiomers and diastereomers. These are common molecular compounds with different.. Key terms: Reset Stereoisomers that are not mirror images of each are _____ .
meaning "opposite," and μέρος, meaning "part" or "portion") is one of two stereoisomers that are nonsuperimposable complete mirror images of each other .
Chapter 5 5 Chiral Carbons • Carbons with four different groups attached are chiral. • It’s mirror image will be a different compound (enantiomer).
1 stereoisomers! Molecular stereoisomers that are nonsuperimposable mirror images are called 1 enantiomers • An enantiomer possesses the property of molecular chirality . Enantiomers • Usually have 4 different functional groups bonded to an sp 3-hybridized atom. That atom is referred to as a 1 Stereogenic center 1 Stereocenter 1 Chiral center
These conditions result in stereoisomers that are also nonsuperimposable mirror images, and, thus constitute a pair of enantiom- Chapter 5 4 Stereoisomers Enantiomers: Nonsuperimposable mirror images, different molecules with different properties.
B) cis-trans isomers. C) diastereoisomers. D) enantiomers. E) geometric isomers. Stereoisomers that aren't mirror images of each other are called diastereomers. The prefix "dia-" is often used to indicate "opposite directions," or "across," as in diagonal. The cis/trans isomers of 2-butene, for example, are stereoisomers, but they are not mirror images of each other.

Diastereomers are stereoisomers that are not mirror images of one another and are non-superimposable on one another. Stereoisomers with two or more stereocenters can be diastereomers. It is sometimes difficult to determine whether or not two molecules are diastereomers. Enantiomers are nonsuperimposable mirror images.
Enantiomers are chiral molecules that are mirror images of one another. Furthermore, the molecules are non-superimposable on one another.

In chemistry, an enantiomer is one of two stereoisomers that are nonsuperimposable complete mirror images of each other. The situation is analogous to a person's left and right hands, which are nonsuperimposable mirror images ; How to Recognize R/S Enantiomers.
Enantiomers • Usually have 4 different functional groups bonded to an sp 3-hybridized atom. That atom is referred to as a 1 Stereogenic center 1 Stereocenter 1 Chiral center A _____ compound has always has an enantiomer (a nonsuperimposable mirror image); an _____ compound always has a mirror image that is the same as the original molecule. Definition 1) Chrial Enantiomers are non-superimposable mirror images of each other. Pardon me while I push the Caps Lock button: Enantiomers always have opposite r,s designations . enantiomer (plural enantiomers). (chemistry) One of a pair of stereoisomers that is the mirror image of the other, but may not be superimposed on this other stereoisomer. A and B are nonsuperimposable mirror images: in other words, enantiomers.
Key terms: Reset Stereoisomers that are not mirror images of each are _____ . The chemical and physical properties of two _____ are different. Isomers that differ only in the way atoms are oriented in space are _____ . Achiral compounds that contain tetrahedral stereogenic centers are _____ .
Diastereomers.
If the arrangement in space makes the two isomers nonsuperimposable mirror images of each other, we call them optical isomers or enantiomers.
