Which of the following statements is correct regarding stereoisomerism?

Options

  1. ADiastereomers are stereoisomers that are non-superimposable mirror images of each other.
  2. BMeso compounds are optically active because they possess chiral carbon atoms.
  3. CA racemic mixture is optically inactive due to internal compensation.
  4. DEnantiomers possess identical physical properties such as melting point, boiling point, and refractive index.

Correct answer

D. Enantiomers possess identical physical properties such as melting point, boiling point, and refractive index.

Step-by-step solution

Diastereomers are stereoisomers that are not mirror images of each other. Meso compounds contain chiral centers but are optically inactive due to the presence of a plane or center of symmetry, which leads to internal compensation. A racemic mixture is an equimolar mixture of two enantiomers and is optically inactive due to external compensation. Enantiomers have identical physical properties such as melting point, boiling point, density, and refractive index. They only differ in their interaction with plane-polariz
