Q.

Arrange the bonds in order of increasing ionic character in the molecules. LiF,K2O,N2,SO2 and CIF3.              [2024]

1 ClF3<N2<SO2<K2O<LiF  
2 LiF<K2O<ClF3<SO2<N2  
3 N2<SO2<ClF3<K2O<LiF  
4 N2<ClF3<SO2<K2O<LiF  

Ans.

(3)

More is electronegativity difference between atoms more will be the ionic character of the molecule. So, the order of increasing ionic character in the given molecules is N2<SO2<ClF3<K2O<LiF.
