Answer:

Correct Answer: 38. (3)

Solution:

  1. Molecules that are non-superimposable on its mirror image are optically active and known as chiral molecule. However, for chirality of molecule, presence of chiral centre is not essential, e.g.

Molecule is chiral but does not possesses any chiral carbon.
