Remember that a chemical species is an atom/molecule with a … WebEnantiomers are stereoisomers that are non-superimposable mirror images. Enantiomers differ at the configuration of every stereocenter. They can be understood in terms of handedness, like gloves for the right or left hands. Molecules that are not mirror images but differ in spatial arrangements of atoms are diastereomers.
