What is the term for a molecule that can rotate the plane of polarized light?
- A. Chiral (optically active) molecule ✓
- B. Achiral molecule
- C. Racemic mixture
- D. Meso compound
Correct answer
A. Chiral (optically active) molecule
Explanation
A chiral molecule lacks a plane of symmetry and rotates plane-polarized light, making it optically active; a racemic mixture (equal enantiomers) does not rotate light net.
