Question

Assertion. `PbI_(4)` is a stable than `PbCl_(4)`.
Reason. Iodide ion stabilizes higher oxidation state.
A. If both assertion and reason are true, and reason is the true explanation of the assertion.
B. If both assertion and reason are true, but reason not is the true explanation of the assertion.
C. If assertion is true, but reason is false.
D. If both assertion and reason are false.

Answer 1

Correct Answer - D
Correct assertion. `PbI_(4)` is unstable.
Correct reason. `I^(-)` being a reducing agent, reduces `Pb^(4+)` to `Pb^(2+)` or `Pb^(4+)` being an oxidising agent oxidises `I^(-)` to `I_(2)`.
