Q. Unstable lead compounds are
A) $PbCl_{4},PbBr_{4}\ and\ PbI_{4}$
B) $PbCl_{2},\ PbBr_{2}and\ PbI_{2}$
C) $PbO,\ PbO_{2}\ and\ Pb_{3}O_{4}$
D) ${PbCl}_{4}^{2 -},\ {PbCl}_{6}^{2 -}$
Explanation
(a)
Lead is found to be stable in +2 oxidation state, due to inert pair effect hence,
$PbCl_{4},\ PbBr_{4}$ and $PbI_{4}$ are less stable compounds
