Question

Assertion :$CC{l}_4$ is stable while $PbC{l}_4$ is powerful oxidizing agent. Reason: Due to the inert pair affect the stability of the $+2$ state increases on moving down the group from carbon to lead.

• A. Assertion is true, Reason is true and Reason is correct explanation for Assertion
• B. Assertion is true, Reason is true and Reason is NOT the correct explanation for Assertion
• C. Assertion is true, Reason is false
• D. Assertion is false, Reason is true

Answer 1

The correct option is A

Assertion is true, Reason is true and Reason is correct explanation for Assertion

Carbon tetrachloride is stable because usually, $C$ forms compounds with a $+4$ oxidation state. But as we move down the group, the $+2$ oxidation state becomes more stable than $+4$ oxidation state due to inert pair effect.

Hence, $Pb\left(IV\right)$ easily converts to $Pb\left(II\right)$ oxidation state and hence, it acts as strong oxidizing agent.

So, the correct option is $A$
