Answer 1

Enantiomers are non-superimposable mirror images of each other with a chiral center, while diastereomers are stereoisomers that are not mirror images and thus have different physical and chemical properties. Optical isomers, a category including enantiomers, exhibit unique biological activities due to their ability to rotate polarized light.

Step-by-step explanation:

Enantiomers are stereoisomers that are non-superimposable mirror images of each other and possess chirality, which means they have a carbon atom with four different atoms or groups attached to it, leading to two mirror image forms that cannot be overlaid on one another. Examples include D-glucose and L-glucose, or D-alanine and L-alanine. Diastereomers, on the other hand, are stereoisomers that are not mirror images and therefore have different physical and chemical properties.

To distinguish between these types of stereoisomers, it's important to consider the presence of chiral centers and the spatial arrangement of substituents. Diastereomers will typically not have all the chiral centers in opposite configurations as their counterpart, which leads to differences in their physical and chemical properties. Meanwhile, optical isomers like enantiomers are known for their ability to rotate plane-polarized light due to their chiral nature and these can have drastic differences in biological activity.

Answer 2

Hello. You did not show the pairs of compounds to which the question refers, which makes it impossible for them to be classified as enantiomers or diastereomers. However, I will try to help you in the best possible way.

To find out if the compounds are enantiomers or diastereomers, you must evaluate their structure in relation to each other. This is because enantiomers, will be the pairs of compounds that have very similar structures, reaching the point of looking like mirrored structures of each other, but they cannot overlap. On the other hand, diastereomers are neither able to overlap, nor have such similar structures.
