Chemistry Question on Isomerism
R and S enantiomer are differ in:
A
Rotation of PPL
B
Solubility in achiral solvent
C
Chemical properties
D
Dipole moment
Answer
Rotation of PPL
Explanation
Solution
The Rotation of plane-polarized light (PPL) is a fundamental property used to distinguish between R and S enantiomers. These enantiomers are mirror images of each other, and their specific rotations are in opposite directions due to the difference in their three-dimensional arrangement of atoms or groups. This difference in optical activity (rotation of PPL) is a key characteristic of enantiomers.
So, the correct option is (A): Rotation of PPL
