In simpler terms – your hands are enantiomers of each other. Even though both hands are identical to one another, one cannot have the same hand if you try to place the right hand on top of the left hand.

Armodafinil consists purely of the R-enantiomer of Modafinil, whereas Modafinil consists of both the enantiomers. That is why Armodafinil is called the enantiopure compound of Modafinil.
