Step 1
This problem can be solved by using a Fajan's rule of polarization in inorganic chemistry.
According to this rule,
" Covalent character is inversely proportional to boiling point"
And for Cation
Covalentnt character proportional to charge on cation and inversely proportional to size of cation.
And For Anion
Covalent character proportional to charge and size of anion
