What is an Enantiomer?
Enantiomers are the stereoisomers having non-superimposable mirror images. They have proximate melting and boiling points and can be distinguished by passing plane polarised light on them. Based on their absolute configuration, we can classify them as “left-handed” and “right-handed”.

Enantiomers Practice Problems
Question 1: Are these molecules enantiomers, diastereomers or the same?
Answer:
The molecules discussed above are enantiomers because it has a non-superimposable mirror image relationship.
Question 2: Are these molecules enantiomers, diastereomers or the same?
Answer:
The molecules discussed above are diastereomers because it has a non-superimposable non-mirror image relationship.
Question 3: Are these molecules enantiomers, diastereomers or the same?
Answer:
The molecules discussed above are enantiomers because it has a non-superimposable mirror image relationship.
Use the following structures to answer the questions.
Question 4: Which of these molecules are enantiomers of each other?
Answer:
Molecules 1 and 2, 3 and 4 represent pairs of enantiomers as they have a non-superimposable mirror image relationship.
Question 5: Which of these molecules are diastereomers of each other?
Answer:
Molecules 1 and 3, 1 and 4, 2 and 3, 2 and 4 represent pairs of diastereomers as they have a non-superimposable non-mirror image relationship.
Frequently Asked Questions on Enantiomers Practice Problems
What is an enantiomer?
Enantiomers are the stereoisomers having non-superimposable mirror images. They have proximate melting and boiling points and can be distinguished by passing plane polarised light on them. Based on their absolute configuration, we can classify them as “left-handed” and “right-handed”.
What is a diastereomer?
Diastereomers are the stereoisomers having non-superimposable non-mirror images. They have distinct melting and boiling points.
What is the difference between enantiomers and diastereomers?
Enantiomers are the stereoisomers having non-superimposable mirror images. They have proximate melting and boiling points. In contrast, diastereomers are the stereoisomers having non-superimposable non-mirror images. They have distinct melting and boiling points.
What is a racemic mixture?
A homogeneous mixture of comparable quantities of two enantiomers is a racemic mixture. A racemic mixture shows distinct properties from the enantiomer.
Are enantiomers chiral?
Enantiomers are the stereoisomers having non-superimposable mirror images. They are chiral as they cant be superimposed on their mirror image.
