Answer :
Answer:
Stereoisomers that are not mirror images of each are diasteroisomer . The chemical and physical properties of two diasteroisomers are different. Isomers that differ only in the way atoms are oriented in space are Stereoisomers . Achiral compounds that contain tetrahedral stereogenic centers are meso isomers . Isomers that differ in the way the atoms are connected to each other are structural isomer . Stereoisomers that are nonsuperimposable mirror images of each other are enantiomers . The chemical and physical properties of two enantiomers are identical except in their interaction with chiral substances.
Explanation:
Diasteroisomers are differentiated by the spatial arrangement of atoms, but they are not specular images so they are not enantiomers. In order for two molecules to be diastereoisomers, they must have at least two chiral centers. In one of the centers the substituents are arranged equally in both molecules and in the other they must change.
Enantiomers are specular images but are not superimposable. They have the ability to rotate the polarized light plane
The stereoisomers present the same molecular formula but different spatial rearrangement between their atoms, we can mention the cis and trans isomers where the cis isomers are on the same side of the plane and the trans isomers on opposite sides. They are also known as geometric isomers.
Meso compounds always have more than one asymmetric center and are aquiral. They are distinguished because they present a plane of symmetry.
Structural isomers are those that have different connectivity between their atoms. We can differentiate, for example, metoximethane from ethanol. They will always have the same molecular formula.
