Stereoisomers, diastereomers, enantiomers For a chiral or asymmetric carbon there are 2 forms. In general a molecule with m chiral centers will have 2 (m) stereoisomers. The multiple stereoisomeric forms means that not all stereoisomers will be mirror images of each other

Stereoisomers that are not mirror images of each other are called diastereomers D-glyceraldehyde and L-glyceraldehyde are mirror images of each other, called enantiomers and stereoisomers at the same time and cannot be superimposed on each other
