Which of the following statements most accurately describes the characteristics of diastereomers, enantiomers, and meso compounds?
  • a)
    Diastereomers, which are stereoisomers not related by reflection or non-superimposable non-mirror images, are similar to other isomers in having distinct chemical and physical properties.
  • b)
    The chemical properties of enantiomers, including both the qualitative reactions and the quantitative rates of reaction, are identical when reacting with other chiral chemical species.
  • c)
    For a given set of stereoisomers, meso compounds must have at least 2 stereocenters and are diastereomeric to the other stereoisomers in the set.
  • d)
    Enantiomers rotate plane polarized light and in opposite directions, while meso compounds are achiral and do not rotate plane polarized light.
Correct answer is option 'C'. Can you explain this answer?

  • Enantiomers share the same physical properties except for their ability to rotate plane-polarized light. Enantiomers share the same chemical properties except when reacting with a chiral reagent.
  • To elaborate, any chiral stereoisomers rotates plane-polarized light, but enantiomers rotate in a specific relationship, in opposite directions and in equal magnitude. If the S enantiomer rotates light +50°, then the R enantiomer rotates light -50°.
  • Diastereomers are stereoisomers that are not related by reflection, but diastereomers share similar chemical properties and have distinct physical properties that allow them to be separated by physical means.
  • The correct statement is that meso compounds must have at least 2 stereocenters and are diastereomeric to the other stereoisomers. Do not confuse that with meso compounds having an internal plane of symmetry.

Which of the following statements most accurately describes the charac...
Statement: For a given set of stereoisomers, meso compounds must have at least 2 stereocenters and are diastereomeric to the other stereoisomers in the set.

Explanation:

Definition of Diastereomers:
- Diastereomers are stereoisomers that are not mirror images of each other and are not superimposable.
- They have different chemical and physical properties, including different melting points, boiling points, and solubilities.
- Diastereomers can have different reactivities in chemical reactions.

Definition of Enantiomers:
- Enantiomers are stereoisomers that are mirror images of each other and are non-superimposable.
- They have identical chemical and physical properties, except for their interaction with other chiral molecules.
- Enantiomers have opposite optical activities, meaning they rotate plane-polarized light in opposite directions.
- The qualitative reactions and rates of reactions with other chiral chemical species may differ for enantiomers.

Definition of Meso Compounds:
- Meso compounds are a special type of stereoisomer that contain chiral centers but are achiral as a whole.
- They possess an internal plane of symmetry, which cancels out the chirality of individual chiral centers.
- Meso compounds do not rotate plane-polarized light because they lack overall chirality.
- Meso compounds are diastereomeric to other stereoisomers in a set because they are not mirror images of any other stereoisomer in the set.

Explanation of the Correct Statement:
- The correct statement (option C) accurately describes meso compounds as having at least two stereocenters and being diastereomeric to the other stereoisomers in the set.
- This is because meso compounds possess chiral centers but are achiral as a whole, due to the presence of an internal plane of symmetry.
- The presence of a plane of symmetry differentiates meso compounds from enantiomers, which lack a plane of symmetry and are mirror images of each other.
- Diastereomers, on the other hand, are stereoisomers that are not mirror images of each other and can have different chemical and physical properties. Meso compounds fit this definition of diastereomers because they are not mirror images of any other stereoisomer in the set.

Conclusion:
- The correct statement (option C) accurately describes the characteristics of diastereomers, enantiomers, and meso compounds.
- Diastereomers have distinct chemical and physical properties, enantiomers have identical chemical properties but differ in their interaction with chiral molecules, and meso compounds are achiral with at least two stereocenters and are diastereomeric to other stereoisomers in a set.
