Problem
Assertion
:
PbI
4
\text{PbI}_4
PbI
4
doesn't exist and converts into
PbI
2
\text{PbI}_2
PbI
2
and
I
2
\text{I}_2
I
2
spontaneously at room temperature but
PbCl
4
\text{PbCl}_4
PbCl
4
needs heating to convert into
PbCl
2
\text{PbCl}_2
PbCl
2
and
Cl
2
\text{Cl}_2
Cl
2
.
Reason
:
Pb
2
+
\text{Pb}^{2+}
Pb
2
+
is more stable than
Pb
4
+
\text{Pb}^{4+}
Pb
4
+
due to inert pair effect.
