Thalidomide and l-dopa, shown below, are examples of pharmaceutical drugs that occur as enantiomers, or molecules that are mirror images of one another

Explanation;

-Enantiomers are chiral molecules that are mirror images of one another. Furthermore, the molecules are non-superimposable on one another. This means that the molecules cannot be placed on top of one another and give the same molecule. Chiral molecules with one or more stereocenters can be enantiomers.

Enantiomers have identical chemical and physical properties in an achiral environment. They rotate the direction of plane polarized light to equal, but opposite angles and interact with other chiral molecules differently.
