Which of the following is/are optically inactive?
A)a 50-50 mixture of R and S enantiomers
B)a meso compound
C)every achiral compound
D)a racemic mixture
E)all the above

Question

Quizplus · Accepted Answer

All the options listed are optically inactive. A 50-50 mixture of R and S enantiomers (racemic mixture) is optically inactive because the optical activities of the enantiomers cancel each other out. A meso compound is optically inactive due to its internal plane of symmetry, leading to internal compensation of optical activity. Every achiral compound is inherently optically inactive as it lacks chirality, which is necessary for optical activity.
