MCQ
Assertion : $Pb^{4+}$ compounds are stronger oxidizing agents than $Sn^{4+}$ compounds.

Reason : 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 Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
  • B
    If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
  • ✓
    If the Assertion is correct but Reason is incorrect.
  • D
    If both the Assertion and Reason are incorrect.
✓

Answer

Correct option: C.
If the Assertion is correct but Reason is incorrect.
c
Assertion is true because lower oxidation state becomes more and  more stable for heavier elements in $p-$ block due to inert pair effect. Hence Reason is false.
