Question

Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R

Assertion (A) : $Pb ^{4+}$ can be reduced easily to $Pb ^{2+}$.

Reason (R) : $Pb^{2+}$ is paramagnetic

In the light of the above statements, choose the correct answer from the options given below

• A. Both Assertion and Reason are true and Reason is the correct explanation of Assertion
• B. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
• C. Assertion is true but Reason is false
• D. Assertion is false but Reason is true

Answer 1

Answer: (B)

Both Assertion and Reason are true but Reason is not the correct explanation of Assertion

Answer 2

When ns electrons of outermost shell do not participate in bonding, it is called inert pair effect. Since the inert pair effect increases down the group, therefore Pb compounds are more stable than Pb compounds. Pb compounds thus, act as oxidizing agent.
