Q. Stability of $Ge ^{2+}, Sn ^{2+}$ and $Pb ^{2+}$ is in order
Chemical Bonding and Molecular Structure
A
$Ge ^{2+}> Sn ^{2+}> Pb ^{2+}$
B
$Sn ^{2+}> Ge ^{2+}> Pb ^{2+}$
C
$Pb ^{2+}> Sn ^{2+}> Ge ^{2+}$
D
$Sn ^{2+}> Pb ^{2+}> Ge ^{2+}$
Solution:
Due to inert pair effect in case of lower oxidation state, stability increase down the group.
