(a)
Interpretation:
Whether the given molecule is chiral or achiral is to be determined.
Concept introduction:
A molecule is chiral if it is nonsuperimposable on its mirror image. If the molecule and its mirror image are superimposable, the molecule is achiral.
If rotation of a group attached to a chiral center makes the mirror image superimposable on the original, the molecule is achiral.
(b)
Interpretation:
Chirality of the molecules is to be determined.
Concept introduction:

(c)
Interpretation:
Chirality of the molecules is to be determined.
Concept introduction:
A molecule is chiral if it is nonsuperimposable on its mirror image. If the molecule and its mirror image are superimposable, the molecule is achiral.
If rotation of a group attached to a chiral center makes the mirror image superimposable on the original, the molecule is achiral. A molecule must contain at least one chiral center to be a chiral molecule.
