Q. Find out the correct order of ionic character in the following molecules
(i) $SO _{2}$
(ii) $K _{2} O$
(iii) $N _{2}$
(iv) $LiF$

TS EAMCET 2020

Solution:

Ionic character in a molecule increases with increasing electronegativity difference in bonded atoms.
$\underbrace{ LiF > K _{2} O > SO _{3}}_{\begin{array}{c}\text { Polar } \\ \text { (tonic bond) }\end{array}}>\underbrace{ N _{2}}_{\begin{array}{c}\text { Non-polar } \\ \text { (Covalent bond) }\end{array}}$
