Question

Which of the following statement is true about enantiomers of 2-Chloropropanoic acid?

• A. They have same solubility in water
• B. They have same boiling point
• C. They have same refractive indices
• D. They have same magnitude of angle of rotation of plane polarised light and its direction

Answer 1

Answer: (A), (B), (C)

They have same refractive indices

Enantiomers have identical physical and chemical properties.
For example: Density, melting point, boiling point, refractive index, solubility and dipole moment.

Chemical properties like stability and reactivity will also be identical.
They cannot be separated by physical methods like distillation.

The magnitude of the angle of rotation of plane polarised light is identical in enantiomers, but the direction is opposite.

Thus, statements (a), (b) and (c) true.
