DRILLS ON STEREOCHEMISTRY
2) Enantiomers are:
A) molecules that have a mirror image.
B) molecules that have at least one stereogenic center.
C) non-superposable molecules.
D) non-superposable constitutional isomers.
E) non-superposable molecules that are mirror images of
each other.
1) Cis-trans isomers are:
A) diastereomers.
B) enantiomers.
C) stereoisomers.
D) constitutional isomers.
E) More than one of these choices.
3) How many stereogenic centers are in the following compound:
Question type: True/False
120) A molecule must possess at least one stereogenic center to be a chiral molecule.
124) A racemic mixture will show a depressed boiling point as the impure mixture
creates al owering in the vapor pressure above the solution.
125) A diastereomeric mixture can be very difficult to purify as both isomers have the
same physical properties
