Statement 1: ${\mathrm{Pb}}^{4+}$ compounds are stronger oxidising agent than ${\mathrm{Sn}}^{4+}$ compounds.

Statement 2: The higher oxidation states for the group 14 elements are more stable for the heavier members of the group due to 'inert-pair effect'.

Due to inert-pair effect, the higher oxidation states for the group 14 elements are less stable for the heavier members of the group and have a tendency to reduce to lesser oxidation state (i.e., These are stronger oxidation agent).
