If there is no rotation of plane light by a compound in a specific solvent, though to be chiral, it may mean that:If there is no rotation of plane light by a compound in a specific solvent, though to be chiral, it may mean that:

Options

  1. Athe compound is certainly meso
  2. Bthere is no compound in the solvent
  3. Cthe compound may be a racemic mixture
  4. Dthe compound is certainly a chiral

Correct answer

A. the compound is certainly meso

Step-by-step solution

Meso compound like meso tartaric acid is optically inactive due to the presence of planar molecular symmetry. If there is no rotation of plane light by a compound in a specific solvent, though to be chiral, it may mean that:
Related Theory Meso compounds are molecules having multiple stereocenters, but their mirror images are superimposable. Meso compounds have an identical mirror image whereas enantiomers have a non-superimposable mirror image.
