Is Diastereomers Optically Active?

Both of the enantiomers are diastereomers. In each case, the meso compound is not optically active, while its diastereomeric partner is optically active. It is even possible to have diastereomeric pairs in which neither member is optically active. ... They are both meso compounds, and they are both optically inactive.

Are diastereomers optical isomers?

8: Diastereomers differ at one or more atom. These molecules are not mirror images and they are not superimposable. They are optical isomers because they have the same connectivity between atoms but a different arrangement of substituent groups.

Are enantiomers optically active?

Each enantiomer of a stereoisomeric pair is optically active and has an equal but opposite-in-sign specific rotation. Specific rotations are useful in that they are experimentally determined constants that characterize and identify pure enantiomers.
