What is the difference between diastereomers and enantiomers?
What is the difference between diastereomers and enantiomers?
Enantiomers contain chiral centers that are non-superimposable & mirror images. They only come in pairs! Diastereomers contain chiral centers are non-superimposable but are NOT mirror images.
What are examples of enantiomers?
A common example of a pair of enantiomers is dextro lactic acid and laevo lactic acid, whose chemical structures are illustrated below.
What are examples of diastereomers?
Diastereomers are the stereoisomers that are non identical, do not have mirror images, and hence are non-superimposable on each other. Examples of diastereomers include cis and trans-2-butene, D-threose and D-erythrose, 2-chloro,3-bromobutane, and so on.
How do you find enantiomers?
The simplest way to identify an enantiomer is to recognize that two molecules are mirror images of each other. Enantiomers must be mirror images. The molecules in the image above reflect over the bold line, which represents a mirror plane.
How can you differentiate between enantiomer and diastereomer and give example?
Diastereomers are the stereoisomer compounds with molecules that are not mirrored images of one another and are not superimposable. They are non-superimposable mirror images of each other….Enantiomers vs Diastereomers.

What are enantiomers and diastereomers explain with examples?
Enantiomers are stereoisomers that are mirror images of each other. Diastereomers are stereoisomers that aren’t a mirror image of each other. Have identical physical properties except for the ability to rotate plane-polarised light.
What makes a diastereomer?
Diastereomers are defined as non-mirror image, non-identical stereoisomers. Hence, they occur when two or more stereoisomers of a compound have different configurations at one or more (but not all) of the equivalent (related) stereocenters and are not mirror images of each other.
Are diastereomers mirror images?
Diastereomers are stereoisomers that are not related as object and mirror image and are not enantiomers. Unlike enatiomers which are mirror images of each other and non-sumperimposable, diastereomers are not mirror images of each other and non-superimposable.
Are enantiomers mirror images?
Enantiomers are stereoisomers that are non-superimposable mirror images, meaning that one enantiomer will be the mirror image of the other enantiomer.
Can diastereomers be mirror images?
How do you identify a diastereomer?
Among molecules with the same connectivity:
- Molecules that are mirror images but non-superimposable are enantiomers.
- If they aren’t superimposable, and they aren’t mirror images, then they’re diastereomers.
