What is the main difference between enantiomers and diastereoisomers?
What is the main difference between enantiomers and diastereoisomers?
- Enantiomers are mirror images, while diastereoisomers are not mirror images. (correct)
- Enantiomers have different numbers of asymmetric carbons, while diastereoisomers have the same number of asymmetric carbons.
- Enantiomers have the same spatial configuration, while diastereoisomers have different spatial configurations.
- Enantiomers have different structural formulas, while diastereoisomers have the same structural formula.
