Question

Which of the following is NOT true for enantiomers?

• A. They have the same density
• B. They have the same specific rotation
• C. They have the same melting point
• D. They have the same boiling point

Answer 1

Answer: (B)

They have the same specific rotation

Enantiomers are chiral molecules that are mirror images of one another. Furthermore, the molecules are non-superimposable on one another. This means that the molecules cannot be placed on top of one another and give the same molecule. Chiral molecules with one or more stereocenters can be enantiomers. Hence they have equal but opposite specific rotation.
