Some Basic Concepts of Organic Chemistry question

2007 · Q108

NEETChemistrySome Basic Concepts of Organic ChemistryMCQ+4 / −1
If there is no rotation of plane polarised light by a compound in a specific solvent, through to be chiral, it may mean than
  1. A
    the compound is certainly meso
  2. B
    there is no compound in the solvent
  3. C
    the compound may be a racemic mixture
  4. D
    the compound is certainly a chiral.

Correct answer: A

Compounds which do not show optical activity inspite of the presence of chiral carbon atoms are called meso-compounds. The absence of optical activity in these compound is due to the presence of a plane of symmetry in their molecules. e.g. meso-tartaric acid is optically inactive.
