The right order of increase in the ionic character of the molecules, LiF, K2O, N2, SO2, ClF3 is -
1. N2 < SO2 < ClF3 < K2O < LiF
2. N2 > SO2 > ClF3 > K2O < LiF
3. N2 > SO2 > ClF3 > 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. |
