Interpretation:
Whether a coffee mug is chiral or achiral is to be determined.
Concept introduction:
An object is chiral if it is nonsuperimposable on its mirror image.
If an object is superimposable on its mirror image, it is achiral. If an object has a plane of symmetry, it is achiral. A plane of symmetry is a plane that divides the object into two halves that are mirror images of each other.
