For the molecules $\mathrm{LiF},{\mathrm{N}}_2,{ \mathrm{K}}_2\mathrm{O}$ and ${\mathrm{ClF}}_3,$ what is the correct arrangement of bonds in order of increasing ionic character?

Find out the correct order of ionic character in the following molecules

$\left(\mathrm{i}\right) {\mathrm{SO}}_2$     $\left(\mathrm{ii}\right) {\mathrm{K}}_2\mathrm{O}$     $\left(\mathrm{iii}\right) {\mathrm{N}}_2$    $\left(\mathrm{iv}\right) \mathrm{LiF}$

The electronic configuration of element X is $2, 8, 8, 1$ and the electronic configuration of element Y is $2, 8, 7$. Then the type of bond formed between these two elements is

Two elements $\mathrm{A}$ and $\mathrm{B}$ have electronegativities $1.2$ and $3.0$ respectively. The nature of bond between $\mathrm{A}$ and $\mathrm{B}$ would be
