Which of the following species do not exist?

MCQ

A
$\mathrm{PbF}_4$
B
$\mathrm{PbCl}_4$
C
$\mathrm{PbO}_2$
✓
$\mathrm{PbI}_4$

✓

Answer

Correct option: D.

$\mathrm{PbI}_4$

$\mathrm{PbF}_4$ exists but $\mathrm{Pbl}_4$ does not exist as $\mathrm {I_2}$ reduces $\text{Pb(II)}$ to $Pb$ and oxidizes $I$ to $\mathrm {I_2}$. Since, $\mathrm {I_2}$ is not strong reducing agent to reduce Pb(II) to $Pb.$
