Question

Which is more ionic SnCl₂ or SnCl4?

Answer 1

SnCl₂ is more ionic than SnCl₄ :

Reason :
According to Fajan rule compound with more charge has higher tendency to polarise the surrounding atom which tends to introduce a covalent character in molecule. As SnCl₄ show Sn ⁴⁺ oxidation state and tends to have higher positive charge and its size is smaller than Sn ²⁺ i.e Sn^{4 +} polarise Cl- more than the Sn2+ ion i.e SnCl₄ is covalent in nature. Hence SnCl₂ is ionic whereas SnCl₄ is covalent.
