All are True for Stereoisomers EXCEPT

Question

All are true for stereoisomers EXCEPT:
A) A diastereomer is a nonsuperimposable non-mirror image.
B) An enantiomer is a nonsuperimposable mirror image.
C) Diastereomers have different melting points.
D) Diastereomers rotate plane polarized light in equal but opposite directions.
E) None, all are true.

Accepted Answer

Diastereomers do not necessarily rotate plane polarized light in equal but opposite directions; this property is characteristic of enantiomers. Diastereomers can have different optical activities, including different magnitudes and directions of rotation.
