To determine the covalent character of a compound we us FAJANS rule.

The main points are:

1.)The size of anion should be larger

2.)The size of cation must be smaller

3.)The order of charges in both the cation as well as the anion must be larger.

4.)Pseudo configuratons(the one with incomplete octet but complete orbitals eg.Berryllium-it is not having complete octet but its last orbital i.e S is completely filled.)are to be considered as having more covalent character Noble(eg Neon gases.


On the basis of the above theroy you can predict the answers.

which is least ionic: AgCl b. KCl c. BaCl 2 d.CaCl 2
​d) CaCl2 for maximum ionic char there are some conditions 1- low charge 2- large size of cation ans small size of anion approve if useful

c – BaCl 2 because it has more charge density per unit volume and therefore by FAJAN’s rule it is most covalent and least ionic

How to calculate n factor and equivalent mass?
→ change in oxidation number is the best method. → charge on cationic or anionic part → no. of replacable H (hydrogen) atoms → no. of replacable OH
