Question

Which substance has the greatest ionic character?

Solution

Correct option is

 

(i) Covalent character 

                                                          (according to Fajan’s rule)

(ii) Lower the covalent character, higher will ionic character. 

Hence, the order of covalent character is

                   

 has the greatest ionic character.
