Question

Which of the following is a true statement?
Options
A All chiral molecules possess a plane of symmetry.
B All achiral molecules are meso.
C All molecules which possess a single asymmetric center of the S configuration are levorotatory.
D A mixture of achiral compounds will be optically inactive.
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

A mixture of achiral compounds will be optically inactive because each compound individually does not rotate plane-polarized light. Chiral molecules do not have a plane of symmetry, not all achiral molecules are meso (meso is a specific type), and the R/S configuration does not predict the direction of rotation.

Hint

What is the optical activity of achiral compounds?
