Question

If there is no rotation of plane-polarized light by a compound in a specific solvent, thought to be chiral, it may mean that:
(a) The compound is certainly meso
(b) The compound may be a racemic mixture
(c) The compound is certainly not chiral
(d) There's no compound in the solvent

Answer 1

Answer:

b) The compound may be a racemic mixture

Explanation:

The compound may be a racemic mixture because an optically active compound rotates plane polarized light. But due to some external compensation (heat, light, catalyst, solvent etc.), the optically active compound loss their optical activity. The compound then exists as racemic mixture i. e., both d and l form are present in solution due to some intramolecular rearrangement. So, there is no rotation of plane polarized light and compound does not have an asymmetric center and when it again forms the symmetric center both d-and l forms are obtained in equal.
