Application +4 | -1

Arrange the bonds in order of increasing ionic character in the molecules:

LiF,\,\,\,{K_2}O,\,\,\,{N_2},\,\,\,\,S{O_2}\,\,\,{\text{and}}\,\,Cl{F_3}

View answer and explanation

Correct option: A

{N_2} < S{O_2} < Cl{F_3} < {K_2}O < LiF

Option B (

{N_2} < S{O_2} < Cl{F_3} < LiF < {K_2}O

) is correct because ionic character increases with electronegativity difference between the bonded atoms.
