Bacl² has greatest iconic character because:
According to Fajans rule, a compound with low positive charge, large cation and small anion has ionic bond where as a compound with high positive charge, small cation and large anion has covalent bonds.
Explanation : Covalent character × 1 / size of cation
Covalent character × size of anion
Lower the covalent character, higher will be iconic character.
Cl²O contains O²‐ , NCL³ contains N³‐
PbCl² contains Pb²+ and Bacl² contains Ba²+.
Hence,the order of covalent character is
NCl³ , Cl²O,PbCl²,BaCl²
therefore, Bacl² has the greatest iconic character
