Webthese, there will be 2n/2 pairs of enantiomers. Compounds from different enantiomeric pairs are diastereomers. If two (or more) of the stereogenic centers are identical, certain isomers will be achiral. A meso form is an optically inactive, achiral form of a compound with stereogenic centers. WebDespite having stereocenters, it is overlaid on its mirror counterpart and is optically inactive. An achiral compound with chiral centres is known as a meso compound. Although it has two or more stereocenters, a meso compound has an internal plane of symmetry that makes it superimposable on its mirror image and is optically inactive.
