Enantiomers and Diastereomers
Q1. Define Enantiomers.
Ans: Enantiomers refer to chemical compounds that are non-superimposable mirror images. It is a molecule that contains a single atom bounded by four substituents that form enantiomers. They are optical isomers.
Q2. Define Diastereomers.
Ans: Diastereomers refer to chemical compounds that are non-superimposable and not mirror images. They include cis-trans isomers, stereoisomers, and double-bond isomers. They can have more than one chiral center. They are having a different melting, boiling point, and densities.
Q3. State some Similarities between Enantiomers And Diastereomers.
Ans: Some Similarities between Enantiomers And Diastereomers – Enantiomers And Diastereomers are stereoisomers. They both are superimposable. They both are optically active and consist of chiral centers.
Q4. State the type of rotation between Enantiomers And Diastereomers.
Ans: Enantiomers have an equal but opposite angle of rotation while Diastereomers do have an equal angle of rotation, unlike the enantiomers.
Q5. State the separation techniques in Enantiomers And Diastereomers?
Ans: Crystallization or chromatography are not used to separate the molecules of enantiomers while in diastereomers the molecules are separated by fractional distillation and chromatography.
Difference Between Enantiomers And Diastereomers
Difference Between Enantiomers And Diastereomers: Stereoisomers are classified into Enantiomers and Diastereomers. Enantiomers occur from chirality. It is a molecule that contains a single atom bounded by four substituents that form enantiomers. They consist of mirror images of one another. When the two enantiomers consist of the same proportions they are known as a racemic mixture. On the other hand, Diastereomers have ring structures which are chemical compounds having the same molecular formula. They don’t have mirror images of one another. They can have more than one chiral center. They are having different melting, boiling point, and densities.
