Covalent compounds are said to be polar when shared pair of electrons are unequally distributed between the two atoms.

Examples: H2O, NH3, HCl, SO2 , H2S

Covalent compounds are said to be non-polar when shared pair of electrons are equally distributed between the two atoms.

Examples:  H2, Cl2, O2, N2, CH4
