What are enantiomers and diastereomers PPT?


What are enantiomers and diastereomers PPT?

Enantiomer Enantiomer are the chiral molecules that are mirror image of one another. They have same physical properties. Example: d-lactic acid & l-lactic acid. D-lactic acid L-lactic acid. Diastereomer Diastereomers are the stereoisomers that are not the mirror images of each other.

What is the relation between enantiomers and diastereomers?

Enantiomers vs Diastereomers

Enantiomers Diastereomers
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 Distinct physical properties

How do you identify enantiomers diastereomers?

Among molecules with the same connectivity:

  1. Molecules that are mirror images but non-superimposable are enantiomers.
  2. If they aren’t superimposable, and they aren’t mirror images, then they’re diastereomers.

What is Enantiomerism in chemistry?

Enantiomers are a pair of molecules that exist in two forms that are mirror images of one another but cannot be superimposed one upon the other. Enantiomers are in every other respect chemically identical.

What are the properties of diastereomers?

Properties of Enantiomers and Diastereomers

S.No Property Diastereomers
1 Melting point Different Melting point
2 Boiling point Different Boiling point
3 Solubility Different
4 Optical rotation Different values may have the same or opposite sign

What is the meaning of diastereomers?

Definition of diastereomer : a stereoisomer of a compound having two or more chiral centers that is not a mirror image of another stereoisomer of the same compound — compare enantiomer.
