WebChirality is defined as “an object which is asymmetric and cannot be superimposed over its mirror image is known as chiral or stereocenter”. This property is known as chirality. For example- our hands, legs etc. The object which is symmetric in nature and can be superimposed over its mirror image is known as achiral. For example- cube, cone etc.
