Which of the following is / are ionic in nature?
(i) $\mathrm{GeF}_4$ (ii) $\mathrm{SnF}_4$ (iii) $\mathrm{PbF}_4$
iii only
ii, iii only
i only
i, ii only
Solution
Most of the $\mathrm{MX}_4(\mathrm{X}=\mathrm{F}, \mathrm{Cl}, \mathrm{Br}, \mathrm{I})$ are covalent in nature in group 14 element but exception are $\mathrm{SnF}_4$ and $\mathrm{PbF}_4$ which are ionic in nature.
