The right order of increase in the ionic character of the molecules,
 
LiF, K2O, N2, SO2, ClF3 is :

1. N< SO< ClF< K2O < LiF

2. N2 > SO2 > ClF> K2O < LiF

3. N> SO> ClF> K2O > LiF

4. LiF > K2O < ClF3 > SO2 > N2

The favourable factors for the formation of an ionic bond would be:

1. Low ionization enthalpy, High negative electron gain enthalpy, High lattice energy.
2. High ionization enthalpy, High electron gain enthalpy, High lattice energy.
3. Low ionization enthalpy, Low electron gain enthalpy, Low lattice energy.
4. High ionization enthalpy, Low electron gain enthalpy, High lattice energy.
