Solution

Dear Student

SnCl₂is 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 Sn⁴⁺ polarise Cl- more than the Sn2+ ion i.e SnCl₄is covalent in nature.Hence SnCl₂is ionic whereas SnCl₄ is covalent.

Because SnCl₄ is covalent, it is liquid and because SnCl₂ is ionic, it is solid.
