Least ionic compound?
a AgCl
b KCl
c BaCl2
d CaCl2 

how to determine this?

Dear Student,

The ionic character of the molecule/atom is determined by the influence of covalent bond, as size of cations increases ionic character increases as per the given options ranking of covalency is CaCl2 > KCl > BaCl2 > AgCl.

Among the options AgCl cation is smaller with least ionic character hence answer is Option (A)

Regards.

the ans is Agcl because it has least covalent charecter 
  • -4
As the size of the cation increases then the ionic character increases so answer is agcl
