Chemical Bonding
Polarisation is the distortion of the shape of anion by an adjacently placed cation. Which of the following statement is correct?
Arrange the below molecules in order of increasing ionic character.$$LiF$$ $$, \ \displaystyle K_{2}O $$, $$ \displaystyle N_{2} $$, $$ \displaystyle SO_{2} $$ and $$ \displaystyle ClF_{3} $$
The increasing order of ionic character is $$\displaystyle N_2 < SO_2 < ClF_3 < K_2O < LiF $$. As the electronegativity difference increases, the ionic character increases.
