Question

Stereoisomers that are not mirror images of one another and are non-superimposable on one another are called: Diastereomers Enantiomers Stereogenic Meso compounds Symmetrical

Answer 1

Stereoisomers that are non-mirror images and non-superimposable are called diastereomers, while enantiomers are non-superimposable mirror images. The presence of chiral centers creates these isomerism types.

Step-by-step explanation:

Stereoisomers that are not mirror images of one another and are non-superimposable on one another are called diastereomers. Examples of diastereomers are D-erythrose and D-threose or L-threose. On the other hand, enantiomers are stereoisomers that are non-superimposable mirror images of each other, like D and L sugars, which can affect plane polarized light differently. The presence of a chiral center, which lacks any planes of symmetry, is what differentiates these stereoisomers. Notably, compounds with more than one chiral center can have diastereomers, such as the case where not all stereocenters are switched between two configurations, as seen in molecules like cis and trans-1,2-dimethylcyclopropane. Moreover, a meso compound, despite having multiple stereocenters, is achiral due to an internal plane of symmetry, thus not forming enantiomers.

Answer 2

Answer: There is a class of organic compounds which are categorized on the basis of symmetry. Symmetry plays an important role on deciding the physical and chemical properties of the organic compounds. The Diastereomers are put into that kind of stereomers which are not the mirror image to each other and the images can not super imposed on each other.

Stereomers which will have two or more than two stereocenter can form diastereomers,
