However, many objects are non superimposable on
their mirror images For example, your left and right
hand look similar but if you put your left hand on
your right hand by moving them in the same plane,
they do not coincide The objects which are non-
superimposable on their mirror image (like a pair
of hands) are said to be chiral and this property is
known as chirality Chiral molecules are optically
active, while the objects, which are, superimposable
on their mirror images are called achiral
