Solution

The ionic character in a molecule is dependent upon the electronegativity difference between the constituting atoms. The greater the difference, the greater will be the ionic character of the molecule.

${N}_{2}<{\mathrm{SO}}_{2}<{\mathrm{ClF}}_{3}<{K}_{2}O<\mathrm{LiF}$

The Ionic character depends upon the difference in electronegativity (bond polarity).

${N}_{2}$ is a covalent molecule & the difference in electrongegativities are:

|X $_{S}$ – X $_{0}$ | $=$ $1.0$

|X $_{Cl}$ – X $_{F}$ | $=1.0$

|X $_{K}$ – X $_{0}$ | $=2.6$

|X $_{Li}$ – X $_{F}$ | $=3.5$
