(a)
Interpretation:
The given object is to be identified as achiral or chiral. The corresponding assumption is to be stated.
Concept introduction:
An object that is asymmetrical and non-superimposable on its mirror image is known as a chiral object. These types of objects are not identical in all directions. An object that is symmetrical and superimposable on its mirror image is known as the achiral object. These types of objects form two identical halves when cut through the center.
(b)
Interpretation:
The given object is to be identified as achiral or chiral. The corresponding assumption is to be stated.
