Question

Stability of $G{e}^{2+},S{n}^{2+}$ and $P{b}^{2+}$ is in order

• A. $G{e}^{2+}>S{n}^{2+}>P{b}^{2+}$
• B. $S{n}^{2+}>G{e}^{2+}>P{b}^{2+}$
• C. $P{b}^{2+}>S{n}^{2+}>G{e}^{2+}$
• D. $S{n}^{2+}>P{b}^{2+}>G{e}^{2+}$

Answer 1

Answer: (C)

Due to inert pair effect in case of lower oxidation state, stability increase down the group.
