Diastereomers are compounds that contain two or more chiral centres and are not mirror images of each other.. For example, the aldopentoses each contain three chiral centres. Meso Compounds Meso: A molecule that contains chiral centers, but is achiral. Achiral Diastereomers (meso-Compounds) The chiral centers in the preceding examples have all been different. What it means here is that when we have an internal plane that splits the compound into two symmetrical sides, the stereochemistry of both left and right side should be opposite to each other, and therefore, result in If A is a meso compound, it should have two or more stereocenters, an internal plane, and the stereochemistry should be Another case is when we rotate the whole molecule by 180 degree. They do not necessarily have to be two stereocenters, but can have more.The chiral centers in the preceding examples have all been different. Meso compounds are molecules having multiple stereocenters, but their mirror images are superimposable. These two halves reflect each other by the internal mirror. In the first case, there is a 120° rotation around the single carbon-carbon bond. Adopted or used LibreTexts for your course? The main difference between meso compound and enantiomers is that meso compounds have an identical mirror image whereas enantiomers have a non-superimposable mirror image. Also, it has an internal symmetry plane that divides the compound in half. Meso compounds are achiral (optically inactive) diastereomers of chiral stereoisomers. In the case of 2,3-dihydroxybutanedioic acid, known as tartaric acid, the two chiral centers have the same four substituents and are equivalent. As yukelid stated, identical compounds are not diastereomers.

In demonstrating the identity of the two meso-compound formulas, remember that a Fischer projection formula may be rotated 180º in the plane.Beside meso, there are also other types of molecules: 1 has a plane of symmetry (the horizonatal plane going through the red broken line) and, therefore, is achiral; 1 has chiral centers. Two of these stereoisomers are enantiomers and the third is an achiral diastereomer, called a Fischer projection formulas provide a helpful view of the configurational relationships within the structures of these isomers.
