हिन्दीWhich of the following is INCORRECT statement?
Correct answer · Option 4
\( \text{PbF}_4 \) 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.
