Explain the following terms :
Chirality

Explanation

Chirality :
the chirality (Greek for Handedness) refers to asymmetry in a molecule. A molecule is said to be a chiral if : (i) It cannot be divided in two equal halves. (ii) It is non - super imposable in its mirror image molecule.
The chirality is a necessary and sufficient condition for a molecule to be optically active and it is a property of a molecule. For example, 2 - chlorobutane, 2, 3-dihydroxy propanal, bromo chloro iodomethane, 2-Bromo propanoic acid etc. are chiral molecules.
