Concept explainers
(a)
Interpretation:
Whether the given pair of molecules are identical, or enantiomers should be determined.
Concept Introduction:
Identical molecules are the ones with no isomers, neither constitutional isomers nor stereoisomers. Identical molecules have the same structural arrangement of atoms and the same three-dimensional arrangement.
Isomers are the molecules with the same formula but either with different structural arrangement (constitutional isomers) or different three-dimensional arrangement (stereoisomers).
A tetrahedral carbon atom bonded to four different groups is called a chiral center. A Molecule having at least one chiral center is a chiral molecule. Molecules that do not have any chiral centers are called achiral. Identical molecules do not have any chiral centers; therefore, they are achiral.
When the mirror images of a chiral molecule are not superimposable, those mirror images become stereoisomers called enantiomers.

In translational motion, the summation is replaced by an integral when evaluating the partition function.
