Arrange the bonds in order of increasing ionic character in the molecules: LiF, K2O, N2, SO2 and ClF3.
The ionic character in a molecule is dependent upon the electronegativity difference between the constituting atoms. The greater the difference, the greater will be the ionic character of the molecule. On...

The exothermic formation of ClF3 is represented by the equation: Cl2(g) + 3F2(g) ⇋ 2ClF3(g);
(d) : Cl2(g) + 3F2(g) ⇋ 2ClF3(g) ; ΔH = –329kJ. Favourable conditions: (i) As the reaction is exothermic, hence decrease in temperature will favour the forward reaction. (ii) Addition of reactants or...
