Which of the following is INCORRECT statement?

  1. A
    \( \text{SiCl}_4 \) is easily hydrolyzed.
  2. B
    \( \text{GeX}_4 \) (\( \text{X} = \text{F, Cl, Br, I} \)) is more stable than \( \text{GeX}_2 \).
  3. C
    \( \text{SnF}_4 \) is ionic in nature.
  4. D
    \( \text{PbF}_4 \) is covalent in nature.
View Answer & Solution

Correct answer · Option D

\( \text{PbF}_4 \) is covalent in nature.

Explanation

Due to inert pair effect, lower oxidation state becomes more stable down the group, making \( \text{Pb}^{2+} \) more stable than \( \text{Pb}^{4+} \). Hence \( \text{PbF}_4 \) is ionic in nature, not covalent.
