Arrange the bonds in order of increasing ionic character in the molecules: LiF, K _{2} O , N _{2}, SO _{2}, and CIF _{3}.
Arrange the bonds in order of increasing ionic character in the molecules: LiF, K _{2} O , N _{2}, SO _{2}, and CIF _{3}.

Solution:

The difference in electronegativity between constituent atoms determines the ionic character of a molecule. As a result, the greater the difference, the greater the ionic character of a molecule.

As a result, the required ionic character order of the given molecules is

N2< SO2< ClF3< K2O <LiF.
