Which is more ionic SnCl2 or SnCl4?
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 Sn4 + polarise Cl- more than the Sn2+ ion i.e SnCl4 is covalent in nature. Hence SnCl2 is ionic whereas SnCl4 is covalent.
