The Total solution for NCERT class 6-12
Arrange the bonds in order of increasingionic character in the molecules: LiF, K2O, N2, SO2 and ClF3.
The ionic character in amolecule is dependent upon the electronegativity difference between theconstituting atoms. The greater the difference, the greater will be the ioniccharacter of the molecule.
On this basis, the orderof increasing ionic character in the given molecules is
N2 < SO2 < ClF3 < K2O < LiF.
