Question

Statement 1: $P{b}^{4+}$ compounds are stronger oxidising agent than $S{n}^{4+}$ 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’.

• A. If both Statement 1 and Statement 2 are true and the statement 2 is the correct explanation of the statement 1.
• B. Ifboth Statement 1 and Statement 2 are true but statement 2 is not the correct explanation of the statement 1.
• C. If Statement 1 is true but Statement 2 is false.
• D. If Statement 1 is false but Statement 2 is true

Answer 1

Answer: (C)

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).
