Question

what is called chirality?​

Answer 1

Chirality is a property of asymmetry important in several branches of science. The word chirality is derived from the Greek (kheir), "hand," a familiar chiral object. An object or a system is chiral if it is distinguishable from its mirror image; that is, it cannot be superimposed onto it.

Answer 2

Answer:

Chirality essentially means 'mirror-image, non-superimposable molecules', and to say that a molecule is chiral is to say that it's mirror image (it must have one) is not the same as it self. Whether a molecule is chiral or achiral depends upon a certain set of overlapping conditions.
