Quizplus · Accepted Answer

Enantiomers are mirror images of each other, but they are not identical as their 3-dimensional shapes cannot be superimposed. These molecules are non-superimposable mirror images of each other, meaning that they have the same chemical and physical properties, and they interact with other chiral molecules differently.
