Chirality and Enantiomers • Classify molecules as achiral or chiral ⟶ Chiral is NOT superimposable on mirror images ⟶ Achiral is superimposable ▪ Achiral you can pick it up and sit it on top of each other and it is the same, chiral compounds you cannot pick up and sit on top of one another and it be the same • Identify chiral centers ⟶ Chiral centers occur at tetrahedral atoms, a chiral center is bonded to 4 DIFFERENT GROUPS ⟶ There are also stereocentersin which when a g...
