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 These
molecules are optically inactive The above test of molecular chirality can be
applied to organic molecules by constructing
models and its mirror images or by drawing three
dimensional structures and attempting to
superimpose them in our minds
