Question
Which of the following is not a condition for the formation of an ionic compound?Low ionisation potentialHigh electron affinityLarge electronegativity differenceSmall electronegativity difference
Solution
The condition that is not necessary for the formation of an ionic compound is "Small electronegativity difference".
Ionic compounds are formed when there is a large electronegativity difference between two atoms. This large difference allows one atom to completely transfer its valence electron(s) to the other atom, resulting in the formation of positive and negative ions. These ions are then attracted to each other to form an ionic compound.
Therefore, a small electronegativity difference would not favor the formation of an ionic compound.
