Difference Between Chiral and Achiral

WebJul 19, 2024 · Cis/trans stereoisomers may exist as achiral molecules. Example of the chiral molecule, optically inactive. Chiral molecules with only one chiral center always have optical activity. Meso compounds and racemic mixtures are examples where the molecule is chiral but optically inactive. The net rotation of plane-polarized light is zero … WebMay 16, 2024 · 1. 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. Thus you can say because a meso compound has an internal plane of symmetry, it is in fact achiral … WebBut, he shows that when the molecule is rotated, it is still the same molecule. That's why even with the chiral ATOMS, the molecule itself is achiral. You'll see in later videos that this is what is called a meso compound - molecules that have both chiral atoms and a plane of symmetry. A plane of symmetry renders a molecule achiral. granite copper ceramic nonstick cookware
