Arrange the bonds in order of increasing ionic character in the molecules. LiF , K 2 O , N 2 , SO 2 and ClF 3 .

Question

TestHub · Accepted Answer

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.

$N_{2} < {SO}_{2} < {ClF}_{3} < K_{2} O < LiF$

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

$N_{2}$ is a covalent molecule & the difference in electrongegativities are:
|X_S – X₀| $=$ $1.0$
|X_Cl – X_F| $= 1.0$
|X_K – X₀| $= 2.6$
|X_Li – X_F| $= 3.5$
