Statement 1 ~Pb ⁴⁺ compounds are stronger oxidising agents than 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'.

Options

  1. AStatement 1 is true, Statement 2 is true, Statement 2 is a correct explanation for Statement 1.
  2. BStatement 1 is true, Statement 2 is true, Statement 2 is not a correct explanation for Statement 1.
  3. CStatement 1 is true, Statement 2 is false.
  4. DStatement 1 is false, Statement 2 is true

Correct answer

C. Statement 1 is true, Statement 2 is false.

Step-by-step solution

In early p-block, on moving top to bottom, the stability of lower oxidation state increases due to inert pair effect. Pb ⁴⁺ is less stable than Sn ⁴⁺ , making it a better oxidising agent The lower oxidation state for the group 14 elements are more stable for the heavier members.
