Which of the following is incorrect statement?
PbF4 is covalent in nature
SiCl4 is easily hydrolysed
GeX4 (X = F, Cl, Br, I) is more stable than GeX2
SnF4 is ionic in nature
(i) PbF4 is not covalent in nature. Because Pb atom is very & F atom is very small, so according to Fajan's rule, PbF4 is not covalent.
(ii) SiCl4 is not a very stable compound because of steric hindrance thus can be hydrolysed very easily
(iii) GeX4 is more stable than GeX2 as in GeX4 all the orbitals are fully filled.
(iv) SnF4 is ionic in nature. Because F atom is very small & Sn atom is very large, so according to Fajan's rule, it is ionic in nature.
