Which of the mentioned compounds would be most ionic in character?

1. 1. PbCl₄
   2. PbCl₂
   3. SnCl₄
   4. SnCl₂

Why  has the most ionic character?

• This is because Pb is in a +2 oxidation state here, but the charge on non-metal in all other choices is +4.
• The larger the charge on the cation, the greater the covalent nature of the bond, according to Fagan’s rule.
• Because  has a low charge on the cation, it has the most ionic property.

Ionic character:

• The difference in electronegativity between two covalently bound atoms is referred to as an ionic character.
• Calculating the difference in electronegativity between the two atoms is one approach to calculating the ionic nature of a bond—that is, the size of the charge separation in a polar covalent bondΔχ = χB − χA.
• The nature of the link between atoms is described by ionic and covalent properties.
• A molecule having a stronger ionic character than a covalent character, for example, suggests that the atoms have a more reciprocal connection with the electrons that bind them.
