If every stereocenter is the opposite orientation, then it's an enantiomer if not, then it's a diastereomer. If two stereoisomers are mirror images of each other, then it is called enantiomers.ĭiastereomers are not enantiomers these are stereoisomers. Because their atoms are different from the fact that stereoisomers are isomers. If they are not superimposable, and they have not mirrored images of one another, then they're diastereomers. DHT is an example of these- Fun FactsĮnantiomers are molecules that are mirror images but non-superimposable. Saccharide (or sugar) is a biological example in chemistry, and below are the Enantiomers and Diastereomers of throes. The main difference between enantiomers and diastereomers is that the former is a mirror image, but the latter is not a mirror image. Molecules that are not defined as mirror images due to the spatial arrangements of atoms are diastereomers. They can be separated by fractional distillation, chromatography, etc.Įnantiomers differ in the configuration of every stereocenter. They can not be separated by crystallization, chromatography, etc. They have the same R, S-configuration at least at one stereocenter. They always have a different R, S-configuration. There can be several molecules in Diastereomers. In the Enantiomers, the Shapes of molecules are similar.ĭiastereomers have different molecular shapes. They do not have an equal angle of rotation. Not all Diastereomers pass the optical activity. They have equal but opposite angles of rotation. There are plenty of these molecules, as long as they demonstrate the spatial arrangements of atoms that are not mirrored images of each other and that are not superimposable.Ī clear explanation of enantiomers vs diastereomers is tabulated below.Įnantiomers are non-superimposable mirror images of each other.Įnantiomers are mirror images of each other which are known as stereoisomers.ĭiastereomers are also non-superimposable but are not mirror images of each other.ĭiastereomers are not mirrored images of each other which are known as stereoisomers.Īll enantiomers have the same physical and chemical properties except interaction with eight and interaction with other chiral compounds.Īll diastereomers have different physical and chemical properties.Įnantiomers have one or more stereocenters.ĭiastereomers have either two or more than two stereocenters.Īll Enantiomers pass optical activity. When the CH 3 are on the same side, the compound is cis, and when the other is swapped with the Hydrogen atom, we name the compound trans. See, the compounds are identical, but the arrangements are different, and they do not mirror images of each other. See the cis-2-butene and the trans-2-butene structures below: The perfect example of diastereomers is when you look at the cis and trans isomer structures. See the difference below the two molecules have the same formula and the structuring of the atoms, so to identify them, we have to label one the S and the other R, depending on the clockwise configuration of the atoms from the lowest atomic mass to highest atomic mass.ĭiastereomers are the stereoisomer compounds with molecules that do not mirror images of one another and that are not superimposable. The tetrahedral carbon to which the different atoms are attached is called the stereocenter. These atoms must be chemically distinguishable for a molecule to be qualified as a chiral and thus an Enantiomer. A chiral molecule has an image that is not the same as its mirror image and it is typically characterized by a carbon center with 4 different atoms bonded to it. Enantiomers and diastereomers are that the former is found as mirror images while the latter isn't that is the main difference.Įnantiomers are chiral molecules that are mirror images of one another and are not superimposable. On the other hand, Stereoisomers differ in the spatial arrangement of their structures.Īgain the stereoisomers are divided into Enantiomers and Diastereomers. Structural isomers have the same molecular formula but are different in their bond connection and order. There are two types of Isomers: stereoisomers, and structural isomers. Here, we'll learn what the difference is between these types of stereoisomers and how to differentiate between them. This means that they are mirror images of each other, but you can't stack them on top of each other and have them line up exactly the same.Įnantiomers and diastereomers are types of stereoisomers. They are non-superimposable mirror images of each other. Diastereomers are the stereoisomer compounds with molecules that are not mirrored images of one another and are not superimposable. Enantiomers are chiral molecules that are mirror images of one another and are not superimposable.
