Web3. Chiral molecules are asymmetric at one or more centres. Achiral molecules are symmetric at all the centres. 4. Chiral molecules rotate plane polarised light in a … WebChiral molecules are optically active, meaning they rotate polarized light. The non-superimposable mirror images of a chiral molecule are called enantiomers. The interesting thing about enantiomers is that they rotate polarized light in the exact opposite way of each other, so if one enantiomer rotates it +25, the other will rotate it -25.

A meso compound is one which satisfies both of the following criteria: (1) it must have chiral centers and (2) it must have an internal plane of symmetry. On the other hand, an achiral compound is one which has an internal plane of symmetry.
