Periodic Classification and Periodic Properties - Result Question 34
####31. Statement $\mathbf{I} Pb^{4+}$ compounds are stronger oxidising agents than $Sn^{4+}$ compounds.
Statement II The higher oxidation states for the group 14 elements are more stable for the heavier members of the group due to ‘inert pair effect’.

Answer:
Correct Answer: 31. (c)
Solution:
- Statement I is true. Stronger oxidising agent is one which itself can easily be reduced. $Pb^{4+}$ is unstable, due to inert pair effect, can easily be reduced to stable $Pb^{2+}$, hence a stronger oxidising agent than $Sn^{4+}$.
Statement II is false. Due to inert pair effect, the higher oxidation states of group 14 elements becomes less stable for heavier member.
